Question

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

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:

$f = \frac{3}{4}n$

For 12 yards of fabric we have:

$12 = \frac{3}{4}n$

From here, we clear the value of n.

We have then:

$n = \frac{4}{3}12$

$n = 16$

Answer:

16 shirts were sewn
