This week, Mister Campanello got an increase in his salary of 3%. He worked 3 days at his previous salary of $16/hour. Then, he worked 2 days at his new salary. If he works 8 hours per day, how much money did he make this week?

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
