Question

Seoul and her friends went into a bakery and where they sell donuts for $1.25 each and cookies for $0.75 each. Seoul has $15 to spend and must buy at least 12 donuts and cookies altogether. If Soul decided to buy 7 donuts, determine the maximum number of cookies that she could buy. .

Answer 1

Answer: 8 cookies

Explanation:

First, we will find the cost of 7 donuts.

7 donuts * $1.25 per donuts = $8.75 for the donuts

Now, we will subtract the cost of the donuts from the money Seoul has.

$15 total - $8.75 for the donuts = $6.25 for the cookies

Next, we will divide the money left by the price per cookie for the number of cookies.

$6.25 for the cookies / $0.75 per cookie = 8
`(1)/(3)` cookies

Lastly, you usually cannot buy one-third of a cookie, so we will round down.

8
`(1)/(3)` cookies ≈ 8 cookies
