dsp73

Answer:40 square yards

Step-by-step 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\times x+40\times (10-x)=480\\60x+400-40x=480\\20x=80\\x=40\ \text{square yards}

Red tiles cover an area of 40 square yards
