p, how many peanut butter bars sold
Q, total number of candy bars sold
Q-p, how many crispy bars sold
R, the sales revenue for all the Q bars sold
L, price for crispy bars
H, price for peanut butter bars

-
Hp%2BLQ-Lp=R
%28H-L%29p=R-LQ
highlight%28p=%28R-LQ%29%2F%28H-L%29%29------quantity of the peanut bars sold

--
H=1.5 dollars per bar
L-1.25 dollars per bar
Q=102 candy bars
R=147.25 dollars

Substitute those into the formula for p.
