O 6 square yards​

Answer 1

Answer:

4 square yards of the floor is covered by the red tiles.

Step-by-step explanation:

Let the area covered by red tiles and white tiles in square yard be x and y respectively.

Given, red tile costs $60/ square yard

and white tile costs $40/ square yard.

60x + 40y = 480 ---(1)

and x + y = 10 ---(2)

Multiplying eq 2 by 40

40x + 40y = 400 ---(3)

Subtracting eq 3 from 1,

60x + 40y = 480

40x + 40y = 400

20x = 80

x = 4 square yards
