$s = (p - 5) (\frac{150 + 0.75 p}{p})$ $s = (p-5)((150+0.75p)/p)$

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

Cost price of each = $\frac{150}{p}$ $150/p$
Selling price = $\frac{150}{p} + 0.75 = \frac{150 + 0.75 p}{p}$ $150/p + 0.75 = (150+0.75p)/p$

Amount received: $s = (p - 5) (\frac{150 + 0.75 p}{p})$ $s = (p-5)((150+0.75p)/p)$

Ami spent $150$150 for pp pennants to sell at the baseball game. She sold all but 55 of them for $0.75$0.75 more than she paid for each one. Write a formula for ss, the amount she received for sales?
