The price of a car was increased from $3,600 to $4,500. What was the percent of the increase?

Answer:

25%

Step-by-step explanation:

.25(3,600)=900

3,600+900=4,500

Answer:

%25

Step-by-step explanation:

First, we need to find increase amount.

4500 - 3600 = 900

To find the percentage of the increase, we need to divide increase amount by initial car price, and multiply the result by 100.

→ 900 / 3600 = 0.25

→ 0.25 * 100 = 25

Todd uses 21 white tiles & some black tiles to make a mosaic.The mosaic has a total area of 144 square centimeters.Each tile has an area of 3 square centimeters.How many black tiles did Todd use?Explain.

Answer: Todd used 27 black tiles.

Step-by-step explanation:

Let x represent the number of black tiles that Todd used.

Todd uses 21 white tiles & some black tiles to make a mosaic. This means that the total number of white and black tiles that Todd used is 21 + x

Each tile has an area of 3 square centimeters. This means that the total area covered by the white tiles is

21 × 3 = 63 square centimeters

Also, the total area covered by the black tiles is

3 × x = 3x square centimeters

The mosaic has a total area of 144 square centimeters. This means that

3x + 63 = 144

3x = 144 - 63

3x = 81

x = 81/3 = 27
