Answer:
She will buy at least 10 pounds or more.
Step-by-step explanation:
If each pound costs $4 and she is spending $40 worth, she needs to buy 10 pounds in order to spend the minimum of $40. She can buy more than 10 pounds to keep spending more money. 11, 12, 13, 14, 15, and so forth are all possible numbers in pounds she will buy.
Take 10% of the snowboard price.
10% = 0.1
109 * 0.1 = $10.90 (10% discount)
109 - 10.9 = $98.10 (Price with discount).
Take 12% of the new snowboard price.
12% = 0.12
98.1 * 0.12 = 11.772 (Round to 11.77)
98.10 - 11.77 = $86.33 (Final discounted price)
Take 6% tax on the new snowboard price.
6% = 0.06
86.33 * 0.06 = 5.1798 (Round to 5.18)
86.33 + 5.18 = $91.51
