Write and solve an equation. You went to lunch with your friend and the bill was $28. Your lunch was four dollars more than your friends how much was your friend's lunch

Answer 1

Let x be the cost of your friend's lunch. Since your lunch was $4 more than your friend's lunch, the cost of your lunch would be x + 4.

The total bill was $28, so the equation would be:
x + (x + 4) = 28
2x + 4 = 28
2x = 24
x = 12

Therefore, your friend's lunch was $12 and your lunch was $16.
