Question

In early spring, you are wanting to purchase 6 potted rose plants. The plants to choose from come in 8-inch pots that sell for $12 and 10-inch pots that sell for $15. If you spend $78, which of the following are the equations for this scenario? Let x = number of 8-inch pots and let y = number of 10-inch pots

Answer 1

We can only buy two kinds of pots, the 8-inch pots or 10-inc pots. The price of each pot multiplied by the total of pots of that kind that we bought must be equal to the total amount we spent. So we can write the first equation as shown below:

$12\cdot x+15\cdot y=78$

The only possible option with this answer is the last one. "x + y = 6 and 12x + 15y = 78".
