Question

You received a ​$100 gift certificate to a clothing store. The store sells​ T-shirts for ​$12 and dress shirts for ​$21. You want to spend no more than the amount of the gift certificate. You want to leave at most ​$7 of the gift certificate unspent. You need at least two dress shirts. What are all of the possible combinations of​ T-shirts and dress shirts you could​ buy?

Answer 1

Answer:

3 dress shirts and 3 T-shirts

4 dress shirts and 1 T-shirt

Step-by-step explanation:

You must spend at least $93 and no more than $100.

2 dress shirts: $42 + 5 T-shirts: $60 = $102 too much money

2 dress shirts: $42 + 4 T-shirts: $48 = $90 too much money left

3 dress shirts: $63 + 3 T-shirts: $36 = $99 this works

4 dress shirts: $84 + 1 T-shirt: $12 = $96 this works

5 dress shirts: $105 too much money

Answer:

3 dress shirts and 3 T-shirts

4 dress shirts and 1 T-shirt
