A store owner bought some flower pots for $1,200. The flower pots were sold for $2,700, with a profit of $30 per pot. How many flower pots did she sell? a. 50 b. 49 c. 47 d. 48

The number of flower pots that were sold is 50

Step-by-step explanation:

Let x represent the number of flower pots that the store owner bought and sold.

A store owner bought some flower pots for $1,200. Therefore, the cost price for each flower pot would be

1200/x

The flower pots were sold for $2,700, with a profit of $30 per pot. The means that the selling price of each flower pot would be

2700/x

Profit = selling price - cost price

Therefore

2700/x - 1200/x = 30

Multiplying both sides of the equation by x, it becomes

2700 - 1200 = 30x

30x = 1500

x = 1500/30 = 50
