The total profit is the sale price of the helmet is $ 60 is:
$ 27,600
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 :
[tex]p(s)=-24s^2+2200s-18000[/tex]
Now we are asked to find the value of p when the s=60
when s=60 we have:
[tex]p(60)=-24\times (60)^2+2200\times 60-18000\\\\\\p(60)=-24\times 3600+132000-18000\\\\\\p(60)=-86400+132000-18000\\\\\\p(60)=27600[/tex]
Hence, the total profit when sale price is $ 60 is:
$ 27,600
