Answer:
In total I had to pay $ 82.42.
Step-by-step explanation:
Since I and my friends went to dinner and I decided to pay for everyone's meal, and the total bill came to $ 65.00, and I decided to give the waiter a 20% tip before tax and also had to pay 6.8% sales tax, for To determine how much did I have to pay in all, the following calculation should be performed:
65 + (65 x 0.2) + (65 x 0.068) = X
65 + 13 + 4.42 = X
78 + 4.42 = X
82.42 = X
Therefore, in total I had to pay $ 82.42.
