Question

Emily sold 78 boxes of cookies for a fundraiser. If she sold 40% of the total number of boxes sold for the fundraiser, how many total boxes of cookies were sold for the fundraiser?

Answer 1

78+78=156(80%) 78/2=39(20%) 156+39= 195 cookie boxes in total

Answer 2

195.

Explanation:

Let x represent the total number of boxes of cookies sold.

We have been given that Emily sold 40% of the total number of boxes sold for the fundraiser.

The number of boxes sold for fundraiser would be
`(40)/(100)x=0.40x`.

Since 78 boxes of cookies were sold for the fundraiser, so we can represent this information in an equation as:

`0.40x=78`

`(0.40x)/(0.40)=(78)/(0.40)`

`x=195`

Therefore, 195 boxes were sold in total.
