A-32.

Write an equation to solve the following problem. Write your answer with a complete sentence.

Susan is buying three different colors of tiles for her kitchen floor. She is buying $107$ red tiles, and three times as many navy blue tiles as beige tiles. If Susan buys $435$ tiles altogether, how many tiles of each color does she buy?

Let $b =$ the number of beige tiles. Your equation should start with “$435 =$” and use $b$ as the only variable.

Choose a number for the amount of beige tiles.

Multiply the number of beige tiles by $3$ to get the number of navy-blue tiles.

Add the beige, red, and navy-blue tiles together to get the total number of tiles Susan bought.
Did your total come out to $435$? If not, try another number for the beige.
