Question

Kristy went shopping and spent $34 dollars on sweaters. If she spent $39 total, what percentage did she spend on sweaters? Round your answer to the nearest percent.

Answer 1

From the sentence, we get these two relations:

$\begin{gathered} 39\to100\text{percent} \\ 34\to x\text{ percent} \end{gathered}$

Which can be rewritten as:

$\begin{gathered} \frac{100}{39}=\frac{x}{34} \\ \end{gathered}$

Solving for x:

$\Rightarrow x=\frac{34\cdot100}{39}=87.17948\ldots$

Now, rounding the answer:

$\Rightarrow x\approx87percent$

After rounding, the answer is 87%
