Question

Matthew decided to bake cupcakes for the school fundraiser. He wants to make 2 dozen cupcakes--one dozen strawberry and one dozen chocolate. He needs 2 1/4 cups of flour for the strawberry cupcakes and 2 1/3 cups of flour for the chocolate cupcakes, but he only has 4 cups of flour. Which two expressions could be used to correctly determine the amount of flour, in cups, Matthew still needs to bake his two dozen cupcakes? 2 part what is the total amount of flour, in cups, Mathew still needs for his cupcakes? NO LINK

Answer 1

`4+c=2(1)/(4)+2(1)/(3),\\\\(7)/(12)\:\text{more cups of flour}`

Explanation:

The total amount of flour, in cups, Matthew needs is equal to
`2(1)/(4)+2(1)/(3)=4(7)/(12)`. Because he only has 4 cups, we can write the following expression to determine how many additional cups of flour he needs:

`4+c=2(1)/(4)+2(1)/(3),\\\\4+c=(7)/(12), \\\\c=\boxed{(7)/(12)\:\text{more cups of flour}}`
