Jake spent 3/80 of his money on a DvD and 1/2 of what was left on a sandwich. He now has $6.25. How much money did he start with?

2 answers

I meant 3/8 of his money
let the original amount be x
he spent 3x/8, leaving him with 5x/8
he spends half of that , leaving him with 5x/16

5x/16 = 6.25
5x = 100
x = 20

He started with $20.00

check: he spends (3/8)(20) or $7.50, leaving him with $12.50
He has 1/2 of that left or (1/2)(12.50) = $6.25
My answer is correct
