Question

The amount of fabric (f) in yards used to sew n number of shirts can be found using the equation f=3/4n

If 12 yards of fabric were used how many shirts were sewn?

Answer 1

For this case we have the following variables:

f: The amount of fabric in yards

n: The number of shirts

The equation modeling the problem is given by:

`f = (3)/(4)n`

For 12 yards of fabric we have:

`12 = (3)/(4)n`

From here, we clear the value of n.

We have then:

`n = (4)/(3)12`

`n = 16`

Answer:

16 shirts were sewn
