Question

PLEASE HELP

Sydney bought 5 new notebooks for $ 1.42 each and 15 pens that cost 3 for $1.20. How much change would Sydney get back if she gave the cashier a $20 bill?

Answer 1

She will get $6.90

Explanation:

5 × 1.42 = 7.10

15 ÷ 3 = 5

5 × 1.20 = 6.00

7.10 + 6.00 = 13.10

20.00 - 13.10 = 6.90
