Hint 2 of 2
Two-step money problems always have this shape: total paid − total spent = change.
Show solution
Approach: find the cost, then subtract from what you paid
- Three apples at 50 cents each: two apples make a dollar, so 3 apples = $1.50.
- Change is the leftover: $5.00 − $1.50 = $3.50.
- Sanity check: $1.50 spent + $3.50 back = $5.00, exactly what she handed over.
