Let's break down the problem step by step to determine which option describes the amount of money Henrietta has in relation to the bicycle purchase.
-
Calculate the sale price of the bike:
- The regular price of the bike is $150.
- The discount is 20% of $150.
- 20% of $150 = 0.20 × 150 = $30.
- Sale price = Regular price - Discount = $150 - $30 = $120.
-
Calculate the sales tax on the sale price:
- Sales tax is 6% of the sale price ($120).
- 6% of $120 = 0.06 × 120 = $7.20.
-
Calculate the total cost of the bike including tax:
- Total cost = Sale price + Sales tax = $120 + $7.20 = $127.20.
-
Compare with the amount Henrietta has:
- Henrietta has $120.
- The total cost of the bike including tax is $127.20.
From these calculations, we can conclude:
- Henrietta does not have enough money even before the tax.
Thus, the correct choice is: c. Henrietta does not have enough money even before the tax.
