Answer: $17,160
Explanation:
Given: Johnny's hourly wage= $8.25
He works 40 hours/week.
Assume 1 year has 52 weeks.
Then, the total amount Johny made in a year = (Hourly wage) x (Number of hours he worked per week) x (Total weeks in a year)
i.e. the total amount Johny made in a year = $ (8.25 × 40× 52)
= $17,160
Hence, Johnny made $17,160 in a year.
