Question

jim bought two shirts originally marked at $40 each. one shirt was discounted 20% and the other was discounted 25%. the sales tax was 4.5%. how much did he spend in all

Answer 1

[(40 x 0.8) + (40 x 0.75)] x 1.045

Answer 2

Multiplying by 0.8 discounts the 1st shirt by 20% (1 - 0.2)
Multiplying by 0.75 discounts the 2nd by 25%
Multiplying the total by 1.045 adds on the sales tax
