Question

Lauren save $84 more than Fiona. 1 fifth Of Lauren's saving was the same as 3 eights of fiona's Saving. How much did Lauren and Fiona save altogether

Answer 1

Lauren's saving=$180

Fiona's saving=$96

Explanation:

Let the saving's of fiona be x

Now given that the savings of lauren is $84 more than fiona which means the saving's of lauren is x+84

Given 1 fifth Of Lauren's saving was the same as 3 eights of fiona's Saving

`(1)/(5)(lauren's saving)=(3)/(8)(fiona's saving)`

`(1)/(5)(x+84)=(3)/(8)(x)`

`8x+672=15x`

`7x=672\\x=96`

Therefore the saving's of fiona is $96 and the saving's of Lauren's is 96+84=$180
