Answer: Total amount earned is $647.68
Step-by-step explanation:
He worked 3 days at his previous salary of $16/hour. If he works 8 hours per day, then the amount he earned working at the previous salary is
16 × 8 × 3 = $384
This week, Mister Campanello got an increase in his salary of 3%. It means that the amount by which his salary increased is
3/100 × 16 = $0.48
His new salary would be
16 + 0.48 = $16.48
If he worked for 2 days at his new salary, then the amount he earned working at the new salary is
16.48 × 8 × 2 = $263.68
Total amount earned is
384 + 263.68 = $647.68
