If Matt buys a cola for $1.69 and gets a refill 3 times at a cost of $0.45 each, which answer best fits the problem?

A. $1.69 + 3 \times 0.45$
B. $1.69 + 3.45$
C. $1.69 + 0.45 \times 3$
D. $3 - 1.69 + 0.45$

First of all, the problem is poorly written. It wants you to find "the answer to the problem", but it doesn't tell you what the question is. Maybe the question is: "How much did Matt spend altogether on cola?", but it never says that.
Furthermore, the answer to that question doesn't appear in the list of choices.
Matt spends ( 1.69 ) pl u s ( .45 three times).
Total cost = 1.69 + 3(0.45) .
Choice 'b' could have worked, if there were parentheses around the ' .45 ', or a 'times' symbol between the ' 3 ' and the ' .45 '. But there's not.

$1.69 + 3 ⋅ $0.45 = $1.69 + $1.35 A n s . 1.69 + 3 ⋅ 0.45

The total amount Matt spends on cola is calculated by adding the cost of his first drink ($1.69) to the cost of the refills ($0.45 each for 3 refills). Therefore, the best answer choices that represent this breakdown are A and C, with A being the clearest representation. Ultimately, the correct set up for the total cost is represented by the expression $1.69 + 3 \times 0.45.
