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
$
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
and this rest money is total cost of markers
so, we can set them equal and then we can solve for x
So, total money in Josie's purse in beginning is $50.4..........Answer
