1. If the make up originally costs $4.30 but is on sale for 40% off, we need to find the sales price

Discount amount = original * discount rate = 4.30 *(.40) = $1.72

Sales price = original price - discount amount = 4.30 - 1.72 = $2.58

2.  So we need to multiply the sales price by the tax rate

Tax amount = sales price * tax rate = 2.58 *(.06) = 0.1548

Final Cost = sales price + tax = $2.58 +$0.1548 = $2.7349 = $2.73

4.30×.6=2.58 which is the discounted price and then add the tax .06, and then you would multiply 2.58×.06=.1548 and then you would add that to 2.58 and get 2.73
