Question

Sally needed to buy some picture frames for her house. The store was running a holiday deal that allowed customers to buy 2 picture frames and get the third for $7. If the total price for all her picture frames was $34, what was the cost of each of the first 2 picture frames?

$34
$11.33
$13.50
$10

Answer 1

Let the price of each of the first two frames be x. For three frames the total is 2x + 7 = 34.
So 2x = 27 and x = 13.50.

Answer: $13.50.
