Answer:
$516
Step-by-step explanation:
Price of lunch: $400
Sales tax: 11% of $400
Tip: 18% of $400
The sales tax and tip combined were 29% of $400 since 11% of $400 + 18% of $400 = 29% of $400.
We calculate the combined sales tax and tip:
29% of $400 =
= 0.29 * $400
= $116
The combined sales tax and tip were $116.
Now we add the combined sales tax and tip to the $400 price of dinner.
total = $400 + $116
total = $516
