We want to find 9.5% of $50.
First put 9.5% in decimal form. 9.5% = 0.095.
Then multiply 0.095 by 50. 50 * 0.095 = $4.75 fee
The money Kennedy will recieve is going to be 50 dollars minus the $4.75 fee.
50 - 4.75 = $45.25 with the fee subtracted
A rectangle, presumably, as the cross section is going to be whatever shape the outward faces are (in the case of a vertical cross section like this one)
The answer is -5x + 4y = -20
