Question

Josh had $10 more than Carly, so he gave Carly half of his money. Then Carly had more than Josh, so she gave Josh $4. Then they both had $13.00. How much money did each person start with. Please show work.

Answer 1

If both have 13 at the end, then there is $26 total.
so write a system:
J = 10 + C
J + C = 26
substitute in J:
10 + C + C = 26
2C = 16
C = 8
so Carly had $8 originally.
Josh had $10 more, so he had $18 originally.
