First, we need to find the area of the larger rug:
15 ft x 16 ft = 240 sq ft
Next, we can set up a proportion using the area and cost:
240 sq ft / $348 = x sq ft / y
We want to find the cost (y) of a 7.5-ft-by-8-ft rug, which has an area of:
7.5 ft x 8 ft = 60 sq ft
Substituting the values we know:
240 sq ft / $348 = 60 sq ft / y
Solving for y:
y = (60 sq ft x $348) / 240 sq ft
y = $87
Therefore, it will cost the family $87 to buy a 7.5-ft-by-8-ft rug.
It costs a family $348.00 to buy a 15-ft-by-16-ft rug. If the cost is proportional to the area,
what will it cost the family to buy a 7.5-ft-by-8-ft rug?
