Question

Maria's dinner bill is $13.53 after tax. If she wants toleave a 15% tip, what will the total cost of thedinner be?

Answer 1

Consider that the total expenditute made by Maria includes the cost (B) of the bill and the tip (T) paid for the dinner.

Given that the bill is $13.53, while the tip is 15% of the bill, the actual amount paid as tip is calculated as,

$T=\frac{15}{100}\times13.53=2.0295\approx2.03$

Then the total cost (C) of the dinner is given as,

$C=B+T=13.53+2.03=15.56$

Thus, the dinner costs $15.56 to Maria.
