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