Question

Cindy works in a cake shop and earns $42 per day. She earns an extra $4 for each cake she sells. If Cindy wants to earn at least $50 per day, which inequality shows the minimum number of cakes, n, that she should sell?

42 + 4n ≤ 50, so n ≤ 2
42 + 4n ≥ 50, so n ≥ 4
42 + 4n ≥ 50, so n ≥ 2
42 + 4n ≤ 50, so n ≤ 4

Answer 1

42+4n ≥ 50, so n ≥ 2

Answer 2

Explanation:

42+4n<50, so n<4
