Answer:
Step-by-step explanation:
Discount on shirt = 40% of 28 =0.40 * 28 = $ 11.20
Sale price = Original price - discount price = 28 - 11.20
= $ 16.80
Discount on jacket = 40% of 98 = 0.40 * 98 = $ 39.20
Sale price = 98 - 39.20
= $ 58.80
Risen amount = 4% of 7 = 0.04 * 7 = $ 0.28
Pay he earns after rise = 7 + 0.28 = $7.28 per hour
Risen amount = 0.04 * 12850 = $ 514
Pay after rise = 12850 + 514 = $ 13364
