Given data:

The given amount Mary got per hour is A=$12 .

The total hours Mary works is H=10 hours.

The percentage of commission Mary got is P=10%=0.1.

The sale amount is S=$1,500.

The expression for the Money earned by Mary is,


E=A* H+P* S

Substitute the given values in the above expression.


\begin{gathered} E=(12)(10)+(0.1)(1,500) \\ =120+150 \\ =270 \end{gathered}

Thus, the amount earned by Mary is $270, so option (D) is correct.
