Question

Julie is buying chocolate chip and oatmeal cookies from the bakery. Chocolate chip cookies cost 25¢ each and oatmeal cookies cost 20c each. She wants to buy a mixture of at least 50 cookies. Julie is planning to spend less than $10. Let: C = number of chocolate chip cookies she can buy. M = number of oatmeal cookies she can buy. Select the system of inequalities that represents this situation.

Answer 1

`\begin{gathered} \text{ Since we have to spend less that \$10} \\ 0.25C+0.20M<10.00 \\ \\ \text{ Since she want to buy at least 50,} \\ C+M\ge50 \\ \\ \text{ The answer is } \\ 0.25C+0.20M<10.00 \\ C+M\ge50| \end{gathered}`
