Question

Brian went shopping and spent $22 on tank tops. If he spent $78 total, what percentage did he spendon tank tops? Round your answer to the nearest percent.

Answer 1

Brian spent a total of $78 while shopping, $22 of which he spent on tank tops.

The total spent is $78, which represents 100% of the money spent.

To determine the percentage spent on the tank tops you can use cross multiplication:

$78 → 100%

$22 → x %

Both relationships are at the same ratio so that:

$\frac{100}{78}=\frac{x}{22}$

Multiply by 22

$\begin{gathered} 22\cdot\frac{100}{78}=22\cdot\frac{x}{22} \\ 28.2=x\to x\cong28 \end{gathered}$

He spent 28% of his purchase on tank tops.
