Question

Rachel is collecting donations for the local animal shelter. So far she has collected $245, which is 70% of what she hopes to collect. How much money does Rachel plan to collect for the shelter?

Answer 1

We know that she has 245, which is 70% of the total. Which can be written as 70/100. We know that 245 is that same percentage of an unknown value.  

We can say then, $\frac{245}{x} = \frac{70}{100}$

We need to cross multiply $24500= 70x$

If we solve for x we get, $x=350$
