Question

A booklet of stamps costs at least $11. Each stamp costs $0.44. The inequality shown can be used to find n, the number of stamps per booklet.

0.44n ≥ 11

Which inequality represents the solution set for this situation?

Responses

A n ≤ 4n ≤ 4

B n ≥ 4n ≥ 4

C n ≤ 25n ≤ 25

D n ≥ 25

Answer 1

Solve 0.44n ≥ 11. Divide both sides by 0.44 (positive), giving n ≥ 11/0.44 = 25.

So the correct inequality is n ≥ 25 — answer D.
