Question

As part of a class project, Mesut collected $126 in donationsfor a local charity. That amount was 7% of the total amountcollected by the class. How much money did the class collectin all?

Answer 1

The total amount can be obtained by the rule of three:

`\begin{gathered} 126\rightarrow7 \\ x\rightarrow100 \end{gathered}`

Then:

`x=(100\cdot126)/(7)=(12600)/(7)=1800`

Therefore the total amount is $1800.
