Solution for problem 28:
First find the price of the hat with % off:
28 - (0.15 × 28) = 23.80
Next find the amount of taxes to be added to the price:
23.80(0.0675) = 1.6065 which rounds to $1.61
Add price and taxes to get total cost:
23.80 + 1.61 = 25.41 → Total cost of the hat is $25.41
Solution for problem 29:
First find price of chair with % off:
325 - (.10 × 325) = 292.50
Now find the taxes on that price:
292.50 × 0.085 = 24.8625 which rounds to $24.86
Now add that to the sale price to get total cost:
292.50 + 24.86 = 317.36 → Total cost of chair is $317.36
