Question

Ami spent `$150` for `p` pennants to sell at the baseball game. She sold all but `5` of them for `$0.75` more than she paid for each one. Write a formula for `s`, the amount she received for sales?

Answer 1

`s = (p-5)((150+0.75p)/p)`

Explanation:

The number of pennants bought = `p`
The number of pennant sold = `p-5`

Cost price of each = `150/p`
Selling price = `150/p + 0.75 = (150+0.75p)/p`

Amount received: `s = (p-5)((150+0.75p)/p)`
