Which problem can be solved using this equation? 2x + 8 = 15? A) Maria bought a notebook for $8 and a magazine. What was the total that she spent? B) Maria bought two notebooks and a magazine for a total of $15. How much change did the clerk give Maria? C) Maria bought a magazine for $8 and 2 notebooks. She spent a total of $15. What was the cost of each notebook? D) Maria bought 2 magazines for $8 each and a notebook. She spent a total of $15. How much did she pay for the notebook?

C) Maria bought a magazine for $8 and 2 notebooks. She spent a total of $15. What was the cost of each notebook?

Step-by-step explanation:

The equation has twice an unknown value added to 8 with the result being 15.

Here are how the answer choices compare to the equation:

A) only one magazine of unknown cost is involved, not two. There is not enough information to answer this question with any equation.

B) three unknowns are involved and the question asks for the difference of their sum and 15. There is not enough information to answer this question with any equation.

C) if x represents the cost of the notebook, the equation is appropropriate to finding its cost, as asked by the question. This is the best choice.

D) only one unknown. The question makes no sense, as she bought items worth more than the amount paid.
