Question

Cooper and his children went into a bakery and where they sell cupcakes for $2.50 each and donuts for $1.50 each. cooper has $40 to spend and must buy a minimum of 18 cupcakes and donuts altogether. if cooper decided to buy 7 cupcakes, determine the maximum number of donuts that he could buy. if there are no possible solutions, submit an empty answer.

Answer 1

Answer: He can buy a maximum of 15 donuts

Explanation: If he bought 7 cupcakes costin $2.50 each then you would multiply 2.50 by 7 which would give you $17.50

then you subtract 17.50 from 40 which gives $22.50 left to use for donuts

then you know you need to have a minimum 18 cupcakes and donuts together so we multiply 1.50 x 11 for the remaining 11 donuts you need and that leaves you with six dollars then if you multiply 1.50 x 4 it gives you the remaining 6 dollars you need so the max number of donuts you may buy is 15

Hope this Helps!
