Question

a construction worker is sent to buy more than 30 lb of rooting nails. the nails are sold in 5 lb boxes and 10 lb boxes. the number of 5 lb boxes is represented by x, and the number of 10 lb boxes is represented by y.

Which inequality models this situation?

A . x + y > 30
B . x + y ≥ 30
C. 5x + 10y > 30
D. 5x + 10y ≥ 30

Answer 1

Since you want more than 30 you can remove the greater than or equal to options.
Since you know that 5x represents the 5lbs and we can assume 10y represents the 10lbs boxes ... the choice should be clear.
