To calculate Sasha's new hourly wage after receiving a 10% raise, we first need to find 10% of his current wage, and then add that amount to his current wage.
10% of $12 can be found by multiplying $12 by 0.10:
\[ 0.10 \times 12 = 1.20 \]
So, Sasha's raise is $1.20.
To find Sasha's new hourly wage, we add his raise to his current wage:
\[ $12 + $1.20 = $13.20 \]
After getting the raise, Sasha will make $13.20 per hour.
