Answer:
$25 = $6.50d
Explanation:
Since d represents the amount of boxes of donuts, you would need to multiply d in the equation by 6.5 or $6.50 since the problem states that 1 dozen donuts costs $6.50 (assuming 1 box contains 1 dozen donuts). $6.50d would have to equate or equal to $25 because the equation 25 = 6.5d shows the most amount of boxes of donuts Tucker could purchase with $25.
If you were wondering, Tucker could purchase up to 3 boxes donuts with $25.
