Answer:
$2.60
Step-by-step explanation:
You can do this two ways.
1) Multiply $8.70 by 2 to find the total cost. Then subtract the total cost from $20.
2) Subtract $8.70 from $20. Then subtract $8.70 from the difference.
Method 1)
$8.70 * 2 = $17.40 is the total cost of the two meals
$20 - $17.40 = $2.60 is the change
Method 2)
$20 - $8.70 = $11.30 is the change after paying for 1 meal.
$11.30 - $8.70 = $2.60 is the final amount of change
Answer: $2.60
