A local bakery has a daily operating cost of $1800 plus a cost of $10 per cake they make. If a cake sells for $15, which inequality could be used to determine the minimum number of cakes, c, they must sell that day to earn a profit?

• 15c < 1800 + 10c

• 15c > 1800 + 10c

• 15c = 1800 + 10c

• 10c < 1800 + 15c
