Question

Josie spent 4/7 of ten money in her purse on some books, and the rest of the money on 18 markers. Each marker cost $1.20. How much money was in Josie's purse to begin with

Answer 1

Let's assume money in Josie's purse to begin with as 'x'

There are 18 markers

Each marker cost $1.20

so, we can find total cost of markers

Total cost of markers = ( total number of markers)*(price of each marker)

so, we can plug value

Total cost of markers is

`=18* 1.20`

`=21.6`$

now, we are given

Josie spent 4/7 of the money in her purse on some books

the rest of the money on 18 markers

so, rest money is

`=x-(4)/(7) x`

`=(3)/(7) x`

and this rest money is total cost of markers

so, we can set them equal and then we can solve for x

`(3)/(7) x=21.6`

`7\cdot (3)/(7)x=21.6\cdot \:7`

`3x=151.2`

`x=50.4`

So, total money in Josie's purse in beginning is $50.4..........Answer
