Question

Brandon and his children went into a bakery and where they sell donuts for $1.25

each and cookies for $0.25 each. Brandon has $5.50 to spend and must buy a
minimum of 10 donuts and cookies altogether. If Brandon decided to buy 2 cookies,
determine the maximum number of donuts that he could buy. If there are no possible
solutions, submit an empty answer.​

Answer 1

The top equation represents Brandon buying 10 donuts and 2 cookies - it’s not possible.
The bottom equation shows Brandon buying 2 cookies and as many donuts as possible (4)

Answer 2

4

Explanation:

Since cookies are $.25 each, and Brandon purchased only 2, you can conclude he has already spent $.50.

If you deduct that from the total, $5.50, you have $5 left. Divide the cost of the donuts, $1.25, and the total to get the answer of 4.
