Question

Payton took a math test with 30 questions, and she answered 24 questions correctly. In order get an A, she needs to answer at least 90 percent of the questions correctly. Did Payton get an A on this math test? Explain.

Answer 1

first we find the percent of the correct questions

30 questions ---> 100%

24 questions ---> x

$\begin{gathered} 30\times x=24\times100 \\ 30x=2400 \\ \frac{30x}{30}=\frac{2400}{30} \\ x=80 \end{gathered}$

Payton get 80 percent, therefore Payton don't get an A on this math test
