To find out how much Alicia will earn for a job that takes 3 hours, we can use the formula provided:
\[ \text{Earnings} = 65h + 100 \]
where \( h \) is the number of hours worked.
Now, we will substitute \( h = 3 \) into the formula:
\[ \text{Earnings} = 65(3) + 100 \]
Calculating this step-by-step:
-
Calculate \( 65 \times 3 \): \[ 65 \times 3 = 195 \]
-
Now add 100 to the result: \[ 195 + 100 = 295 \]
So, Alicia will earn $295 for a job that takes 3 hours.
