Answer 2

0.105

0.11 if you are expected to round to nearest cent.

Explanation:

"of" should be thought of as times.

So you are doing:

`7\% \cdot 1.50`

7% is the same as .07; you could just replace percent with times 1/100 if you don't know. Like this 7%=7*1/100=7/100=.07.

`.07 \cdot 1.50`

When putting this into the calculator you get 0.105.
