Answer:
The total profit is the sale price of the helmet is $ 60 is:
$ 27,600
Explanation:
p denote the total profit and s denote the sale price.
The total profit in terms of the sale price is given by the function :
![p(s)=-24s^2+2200s-18000](https://img.qammunity.org/2020/formulas/mathematics/high-school/vrtysj8xekp91i8pp7oqlpsbp1tnyqx10n.png)
Now we are asked to find the value of p when the s=60
when s=60 we have:
![p(60)=-24* (60)^2+2200* 60-18000\\\\\\p(60)=-24* 3600+132000-18000\\\\\\p(60)=-86400+132000-18000\\\\\\p(60)=27600](https://img.qammunity.org/2020/formulas/mathematics/high-school/pd66kazssakt0p9ckzb0x6omj6m63rqhbz.png)
Hence, the total profit when sale price is $ 60 is:
$ 27,600
