ShoeShop is having a sale on flip-flops. The first 2 pairs cost $8.50 each plus each additional pair costs $3.75. Mrs. Tyler can spend a maximum of $34.75 on flip-flops for her family.

Which inequality can be used to find the number of flip-flops, p, that Mrs. Tyler can purchase from ShoeShop?

To begin this answer, you want to set this up using all the information. You could begin with 8.50 x 2 (first 2 pair) + 3.75p ($3.75 for each additional pair) < (must be less than or equal to) $34.75 (maximum amount she wants to spend). You would simplify this to be 17 + 3.75p < 34.75. Subtract 17 from both sides to get 3.75p < 17.75. Then divide both sides by 3.75 to get p< 4.73 ... You would not be able to purchase more than 4 pair of flip-flops because you can's buy parts of a flip-flop!
