Answer:
a) They would cost the same with 16 tons of sugar.
b) This would cost 9 108 dollar.
Explanation:
! This is only true if the amount of rented trucks remains the same no matter what amount of sugar ! ( Which is really weird but ok.)
a) x= tons of sugar
=>7500+100,50X=6296+175,75X
<=> 75,25x=1204
<=> x=16
b) 7500+100,50.16=9108
