Answer:
231 feet of fabric
Step-by-step explanation:
Gina's curtain company is making curtains for a local hotel. She wants each curtain to be 36 inches long. At the fabric store, fabric is sold by the foot.
Converting from inches to foot
1 inch = 1/12 foot
36 inches = x feet
x = 36 × 1/12 foot
x = 3 feet
Hence, each curtain = 3 feet
If Gina's curtain company wants to make 77 curtains, how many feet of fabric will she need?
This is calculated as:
1 curtain = 3 feet
77 curtains = x
Cross Multiply
x = 77 × 3 feet
x = 231 feet
Hence, she would need 231 feet of fabric
