Well what i think you're asking here...I apologie if I'm wrong but what I did was
f(-1) = 4 * 7^t = 4/7
and
f(2) = 4 * 7^t = 196.
Is this what you wanted if not I can...try another way.
13/95 or 13.7%, pretty straightforward
$20, because when one person is supposed to pay at max. $5, and there are 4 people, 5*4= 20. The maximum cost of their pizza should be $20, so each person pays $5.
