Question

The maximum allowable weight of a trailer with crates is 1000 pounds. The trailer weighs 500 pounds and can carry crates that weigh 25 pounds each. Workers determine that up to 20 crates can be loaded onto the trailer. Which of the following inequalities can be used to support this conclusion? a. 25(20) + 500 >= 1000 b. 25(500) + 20 >= 1000 c. 25(20) + 500 =< 1000 d. 25(20) - 500 =< 1000
