To find out how much Alicia will earn for a job that takes 3 hours, you can use the provided formula:
\[ E = 65h + 100 \]
where:
- \( E \) is the total earnings,
- \( h \) is the number of hours worked.
Now, substituting \( h = 3 \) into the formula:
\[ E = 65(3) + 100 \]
Calculating \( 65(3) \):
\[ 65 \times 3 = 195 \]
Now, add 100 to that amount:
\[ E = 195 + 100 = 295 \]
Therefore, Alicia will earn $295 for a job that takes 3 hours.
