Hello There!

As we h ave the first quiz score provided, we would need to find the score for the second quiz.

Answer:

The correct option is (A).

Step-by-step explanation:

The expression Carey is solving is:

$X=75\%\ \text{of}\ 36$

Simplify the expression as follows:

$X=75\%\ \text{of}\ 36$

$=\frac{75}{100}\times 36\\\\=\frac{3}{4}\times 36\\\\=3\times 9\\\\=27$

So, in Carey's calculation the third step is incorrect.

Instead of 27 the three-fourth must be multiplied by 36 to get the correct answer.

Thus, the correct option is (A).
