3 costumes can be made from 15 feet of fabric
Step-by-step explanation:
The proportion can be sued to solve the following problem
Given
Total fabric = 40 feet
Costumes = 8
Fabric = 15 feet
Costumes = ?
Let x be the number of costumes that can be made with 15 feet of fabric
[tex]Fabric:Costumes::Fabric:costumes\\40:8::15:x\\\frac{40}{8} = \frac{15}{x}\\40x = 15*8\\40x = 120[/tex]
Dividing both sides by 40
[tex]\frac{40x}{40} = \frac{120}{40}\\x = 3[/tex]
Hence,
3 costumes can be made from 15 feet of fabric
