Question

A tailor has 20 yards of shirt fabric.how many shirts can she complete if each shirt requires 2 3/4 yards of fabric?

Answer 1

The length of the shirt fabric is L=20 yards.

The requirement of each shirt is t.

`\begin{gathered} t=2(3)/(4)\text{ yards} \\ =(2*3+3)/(4)\text{ yards} \\ =(11)/(4)\text{ yards.} \end{gathered}`

The number of shirts can be determined as,

`\begin{gathered} N=(L)/(t) \\ =\frac{20\text{ yards}}{(11)/(4)yards} \\ =20*(4)/(11) \\ =(80)/(11)\approx7 \end{gathered}`

Thus, the required number of shirts is 7.

Thus, option (B) is the correct solution.
