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} (100)/(39)=(x)/(34) \\ \end{gathered}`

Solving for x:

`\Rightarrow x=(34\cdot100)/(39)=87.17948\ldots`

Now, rounding the answer:

`\Rightarrow x\approx87percent`

After rounding, the answer is 87%
