Answer:
$64.25 before taxes. $68.75 including the taxes.
Explanation:
For one meal each person paid 1.07 times the price of the meal (includes 7% tax).
Therefore price of each person's meal was 13.75/1.07 = $12.85
Total cost for all 5 meals was therefore $64.25--before taxes. $68.75 including the taxes.
