Question

A builder needs to cover 10 square yards of floor with tile. red tile costs $60 per square yard, and white tole costs $40 per square yard. if the builder spends exactly $480 on tile, how much of the floor will be overed with RED tile?

Answer 1

Answer:40 square yards

Explanation:

Given

Floor area A=10 square yards

Red tile costs
`\$ 60` per square yards

White tile costs
`\$40` per square yards

Total money spent=
`\$480` on tiles

Suppose red tiles cover an area of
`x` square yards

So, we can write

`60* x+40* (10-x)=480\\60x+400-40x=480\\20x=80\\x=40\ \text{square yards}`

Red tiles cover an area of 40 square yards
