How do u find 58% of 702

58% is 58/100

58/100 x 702 = 407.16

You can times 58 and 702 and then divide by 100

58/100 x 702 = 407.16

You can times 58 and 702 and then divide by 100

We set up a proportion: 58/100= ?/702

Cross multiply:

100*?= 58*702

⇒ ?= 58*702/100= 407.16

58% of 702 is 407.16~

Cross multiply:

100*?= 58*702

⇒ ?= 58*702/100= 407.16

58% of 702 is 407.16~

13. Product A is an 8 oz. bottle of cough medication that sells for $1.36. Product B is a 16 oz. bottle of cough medication that costs $3.20. Which product has the lower unit price? And show how you got your answer.

Price / weight = unit price

product A : 1.36 / 8 = 0.17 per oz

product B : 3.20 / 16 = 0.20 per oz

product A has the lower unit price

product A : 1.36 / 8 = 0.17 per oz

product B : 3.20 / 16 = 0.20 per oz

product A has the lower unit price

Rebecca buy some scarves that cost $5 each and two purses that cost $12 each the cost of Rebecca's total purchase is $39 what equation can be used to find an the number of scars that Rebecca buys. A 5 + 24n equals 39. B 5n + 24 equals 39. C (24 + 5)n equals 39. D (24) (5) + n equals 39

Answer:

The answer would be B.

Step-by-step explanation:

the reason that this is the answer is because she spent $24 on purses but that leaves the amount of scarves. she spends $39 all together.

The answer, B.

Step-by-step explanation:

she spent $24 on purses so that leaves the amount of scarves. she spends $39 all together

Find the missing coordinate if the ordered pair is to be a solution to the equation 3x + y = 9

You are given only one equation, but are to find the values of two variables (x and y). No soap.

However, you could arbitrarily let x=1 and then find the corresponding y value.

Then 3(1) + y = 9, so y = 6. One point on this line is (1,6). But there are an infinite number of other solutions.
