Answer:
The cost per case=15.45
Step-by-step explanation:
Step 1
The expression for the total cost of paper cases can be expressed as;
T=C×N
where;
T=total cost
C=cost per case
N=number of cases
In our case;
T=132.87
C=c
N=8.6
replacing;
132.87=c×8.6
8.6 c=132.87
c=132.87/8.6
c=15.45
The cost per case=15.45
