Bobo bought two binders and three staplers for $36. When he got home he realized that he meant to buy three binders and two staplers. If he would have done so, he would have had to pay just $33. What was the cost of each item?
Answer provided by our tutors
let
b = the cost of one binder
s = the cost of one stapler
Bobo bought two binders and three staplers for $36:
2b + 3s = 36
three binders and two staplers cost $33:
3b + 2s = 33
by solving the system of equations:
2b + 3s = 36
3b + 2s = 33
we find:
b = $5.4
s = $8.4
