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

Step-by-step 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 $\frac{1}{3}$ cookies

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

       8 $\frac{1}{3}$ cookies ≈ 8 cookies
