Answer:
Explanation:
If the meal of a family of four were to be $60.00 and they used the coupon. They'd be left with a check for $45.00. After the family adds a tip of 18%, the total adds up to $53.10, with the tip being $8.10
We know the tip is $8.10 because we multiply 45 by .18
45 x .18 = 8.10
We then add the tip to the total
45.00 + 8.10 = 53.10
The final cost of the meal is $53.10
