3. (t^2) - 4
4. (1/5)*s + 4
The volume of a cone uses the following formula:

Our diameter is 20 feet, so divide this by 2 to find the radius:

We now have all of our values need to fill in the formula. Plug in these values:




The volume of the cone is
1780 cubic feet.
T = Total income
N = Number of purses
35N = the selling price of each purse
17N = Cost of each purse
T = 35*N - 17*N - 75
T = 18N - 75
If she wants here total income to be 350 dollars, it will take
T = 350 ; N = unknown.
350 = 18N - 75 Add 75 to both sides.
350 + 75 = 18N
425 = 18N
Rounded N = 24 <<<< Answer. The actually number is 23.611 but you can't sell 0.611 of a purse.
