Answer to Question #98929 in Algebra for Larry

Question

A store manger orders T-shirts so that’s 15 out of every 35 are a medium. How many medium T-shirts would you expect to find when there are 126 T-shirts on a rack

Answer 1

Let $x$ be the number of medium T-shirts out of 126 on the rack. Write down the ratio of medium T-shirts to the total number of T-shirts:

$\frac{15}{35}=\frac{x}{126}$

Multiply across the known corners, then divide by the third number:

$x=\frac{15\cdot126}{35}$ $x=54$

Hence, we expect to find 54 T-shirts on a rack.

Answer: 54 T-shirts
