# Which problem can be solved by division of decimals? Danette needs 8 dozen eggs for her restaurant. How many eggs should she buy? How much money does Dawna need to fill her 11.5 gallon gas tank if the price of gas is \$3.59 a gallon? How many more miles does Judy’s family have to drive to reach their destination if they have driven 45.4 miles of a 123.8 mile trip? What is Jeremy’s average if he received a total of 323.7 points on 7 tests?

The solution is Option D.

What is Jeremy’s average if he received a total of 323.7 points on 7 tests?

The average is 46.24

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

a)

Danette needs 8 dozen eggs for her restaurant. How many eggs should she buy?

The equation is

The number of eggs she should buy for her restaurant is 8 dozen eggs

So , this problem is not solved by division of decimals

b)

How much money does Dawna need to fill her 11.5 gallon gas tank if the price of gas is \$3.59 a gallon?

Total volume of gas tank = 11.5 gallons

Price of 1 gallon = \$ 3.59

The equation is

Price of 11.5 gallons = \$ 3.59 x 11.5

= \$ 41.285

So , this problem is not solved by division of decimals

c)

How many more miles does Judy’s family have to drive to reach their destination if they have driven 45.4 miles of a 123.8 mile trip?

Total miles = 123.8 miles

Miles traveled = 45.4

The equation is

Remaining miles = 123.8 - 45.4

= 78.4 miles

So , this problem is not solved by division of decimals

d)

What is Jeremy’s average if he received a total of 323.7 points on 7 tests?

Total points = 323.7

Number of tests = 7

The equation is

Average of Jeremy's tests = Total points / Number of tests

= 323.7 / 7

= 46.24

So , this problem is solved by division of decimals

Hence , the equation of Jeremy's average is a division of decimal problem

D. What is Jeremy's average if he received a total of 323.7 points on 7 tests?

Step-by-step explanation:

A. Wouldn't be correct because the question does not give you anything to divide by.

B. Wouldn't be correct because the question requires multiplication and not division.

C. Wouldn't be correct because you don't need to divide in this problem but subtract.

D. The reason this is correct is because you would have to divide 323.7 from Jeremy taking 7 tests.  This would give you his average grade.

Maria earns \$60.00 for 8 hours of work and Marc earns \$46.50 for 6 hours of work. Which person earns the most per hour? A. Maria. B. Marc. C. They earn the same amount. D. It cannot be determined.

C. Marc

Step-by-step explanation:

to get the amount they earn in an hour divide the amount they earn by the amount of hours they worked for.

Maria: 60 divided by 8 = 7.50

Marc: 46.50 divided by 6 = 7.75

A store received 300 containers of milk to be sold by February 1. Each container cost the store \$0.79 and sold for \$1.55. The store signed a contract with the distributor in which the distributor agreed to a \$0.50 refund for every container not sold by February 1. If 270 containers were sold by February 1, how much profit did the store make?

The total profit did the store make is \$196.5 and this can be determined by using the formula of profit and using the given data.

Given :

• A store received 300 containers of milk to be sold by February 1. Each container cost the store \$0.79 and sold for \$1.55.
• The store signed a contract with the distributor in which the distributor agreed to a \$0.50 refund for every container not sold by February 1.

The formula of profit is given below:

Profit = Revenue - Expenses    --- (1)

So, first determine the total cost of the 300 containers.

Total Cost = 300 0.79

= \$237

Now, determine the revenue for the 270 sold containers.

Revenue = 270 1.55

= \$418.5

Now, the determine the revenue for the 30 unsold containers.

Revenue = 30 0.50

= \$15

So, the total revenue is given by:

Total Revenue = 418.5 + 15

= \$433.5

Now, substitute the known terms in the equation (1).

Profit = 433.5 - 237

= \$196.5

So, the total profit did the store make is \$196.5.

The question is: If 270 containers were sold by February 1, how much profit did the store make?

Given info:
300 containers total
Cost: \$0.79
Sold: \$1.55
\$0.50 refund (+\$0.50) for containers not sold by Feb 1

Total cost for 300 containers is 300(\$0.79) = \$237

Revenue for the 270 containers would be
270(\$1.55) = \$418.5
Revenue for the 30 unsold containers (due to rebate) is 30(\$0.50) = 15
Total revenue is \$433.50

Profit is revenue - expenses
\$433.50 - \$237 = \$196.5
