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:
[tex] f = \frac{3}{4}n [/tex]
For 12 yards of fabric we have:
[tex] 12 = \frac{3}{4}n [/tex]
From here, we clear the value of n.
We have then:
[tex] n = \frac{4}{3}12 [/tex]
[tex] n = 16 [/tex]
Answer:
16 shirts were sewn
