1. Jesse will have to pay $55.93 in sales tax. $854.93 in total.
(799 x 0.07 = 55.93)
2. Heather will pay $1.25 in sales tax. $26.25 in total.
(11 + 14 = 25. 25 x 0.05 = 1.25)
3. Juan will pay $42.54 in sales tax. $751.54 in total.
(650 + 59 = 709. 709 x 0.06 = 42.54)
4. Patricia left a $3.60 tip.
(24 x 0.15 = 3.60)
5. Logan's father left a $2.80 tip.
(10.50 + 3.50 = 14. 14 x 0.20 = 2.80)
6. The sales price of the DVD will be $16.80.
(24 x 0.30 = 7.20. 24 - 7.20 = 16.80)
