Divide $117 by 6 to get $19.50. Then, add the cost of the appetizer, $6.95, to get $26.45.


Add the cost of the appetizer, $6.95, to $117 to get $123.95. Then, divide by 6 to get about $20.66.

Answer 1

To determine the cost of each main dish, we need to first find the total cost of the appetizers for all 6 friends and then subtract that from the total bill.

Each appetizer costs $6.95, so for 6 friends:
Total cost of appetizers = 6 × $6.95 = $41.70

Now, subtract the total cost of the appetizers from the total bill to find the total cost of the main dishes:
Total cost of main dishes = Total bill - Total cost of appetizers
Total cost of main dishes = $117 - $41.70 = $75.30

Since there are 6 friends, we divide the total cost of the main dishes by 6 to find the cost of each main dish:
Cost of each main dish = Total cost of main dishes / 6 = $75.30 / 6 = $12.55

Thus, the correct response is:
**Divide $117 by 6 to get $19.50. Then, subtract the cost of the appetizer, $6.95, to get $12.55.**
