Let 
represent the number of watermelons purchased. Then 
is the cost per watermelon, and then 
is the sale price per watermelon. 
is the number sold to the breakeven point, so the revenue at the breakeven point is (x\ -\ 100))
. To break even, total revenue must equal total cost:
(x\ -\ 100)\ =\ 750)
Simplify and solve the resulting quadratic for the positive root.
