To find out how much Alicia will earn for a job that takes 3 hours, we can use the formula given:
\[ E = 65h + 100 \]
where:
- \( E \) is her total earnings,
- \( h \) is the number of hours worked.
Given \( h = 3 \):
\[ E = 65(3) + 100 \]
Now, calculate \( 65 \times 3 \):
\[ 65 \times 3 = 195 \]
Now, substitute this back into the equation:
\[ E = 195 + 100 \]
Now, add these amounts:
\[ E = 295 \]
Therefore, Alicia will earn $295 for a job that takes 3 hours.
