Question

Carly is going to bake an apple pie for her grandmother. She went to the grocery store and spent a total of $27.50 on all the ingredients. She wants to know what she spent on one apple.

She spent $23 on all the ingredients excluding the apples, and she bought 3 apples.
Which equation represents the best way to solve for the number of apples she bought, a?

A) 3a = 23
B) 27.50 = 3a
C) 3a + 27.50 = 23
D) 3a + 23 = 27.50

Answer 1

To find the cost of one apple, we use the equation 3a + 23 = 27.50. We then subtract $23 from both sides and divide by 3 to solve for a, representing the price of one apple.

Step-by-step explanation:

The question presented asks how Carly can determine how much she spent on one apple. Carly spent a total of $27.50 on ingredients, including $23 on items other than apples. She bought 3 apples. To find out the cost of one apple, we set up an equation where a represents the cost of one apple. The correct equation to represent Carly's expenditure is D) 3a + 23 = 27.50. This is because Carly spent $23 on other ingredients and 3 times the cost of one apple (3a) plus $23 should equal the total amount spent, which is $27.50. To solve for a, we subtract 23 from both sides of the equation, then divide both sides by 3, giving us the cost of one apple.
