1.5 m3 @ $45 / wk
2.2 m3 @ $55 / wk
3.0 m3 @ $75 / wk
4.8 m3 @ $120 / wk
Select one:
a. One 4.8 cubic meter container
b. Two 2.2 cubic meter containers
c. One 1.5 cubic meter container plus one 3.0 cubic meter container
d. Two 1.5 cubic meter containers
e. One 1.5 cubic meter container plus one 2.2 cubic meter container
