Final answer:
To determine the cost for three more boxes, divide the total cost by the number of boxes to find the price per box, then multiply by three. However, the calculated amount does not match the given options, indicating a potential typo.
Step-by-step explanation:
The student is asking about the cost of buying additional boxes of candy canes given the original cost of five boxes. First, we find the cost of one box by dividing the total cost by the number of boxes:
$9.70 ÷ 5 = $1.94 per box.
Next, to find the cost of three more boxes, we multiply the cost per box by three:
$1.94 × 3 = $5.82.
However, this amount is not listed in the options given. The closest correct option is B. $6.15, which suggests that there might be a small typo in the original problem or options. The step-by-step calculation shows the correct method to determine the cost for three additional boxes based on the given values.
