Question

Higher Order Thinking A railroad car container can hold 42,000 pounds. Mr. Evans wants to ship 90 ovens and some freezers in the same container. If each freezer weighs 600 pounds, how many freezers could be shipped in the container? Explain.

Answer 1

The number of freezers that can be shipped depends on the weight of an oven.

Total Weight: 42000 pounds

Weight of 90 ovens: 90w, where w is the weight of each oven.

Remaining weight to fill with freezers: 42000-90w

Weight of each freezer: 600 pounds

# of freezers that could be shipped: Remaining weight / freezer weight = (42000-90w)/600 = 70-3/20w

ANSWER:
`70-(3)/(20)w`, where
`w` is the weight of each oven
