Answer:
A tuna sandwich for $3.82
Explanation:
1. Pull out the information-
The total is $5.12. He spent $1.30 on a drink. We need to find how much the sandwich was
2. Set up Equation-
s for sandwich
s+1.30=5.12
3. Solve-
Subtract 1.30 from both sides of the equation. This will cancel the 1.30 on the left and leave you with s=3.82
