Question

Susan is buying different colors of titles for her kitchen floor. She is buying 107 red titles, 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?

Answer 1

435 - 107 = 328
328/4 = 82
82 x 3 = 246
246 + 82 = 328 + 107 = 435

So she buys 107 red tiles, 82 beige tiles, and 246 navy blue tiles.
