The Norris

The Norris family goes out for lunch, and the meal price is 52. The sales tax on the meal is 6%, and the family also leaves a 20% tip on the pre-tax amount. What is the total cost of the meal?

Correct answer:

x =  65.52

Step-by-step explanation:

$$\begin{gathered} a=52 \\ {q}_1=6\%=\frac{6}{100}=\frac{3}{50}=0.06 \\ {q}_2=20\%=\frac{20}{100}=\frac{1}{5}=0.2 \\ x=a\cdot (1+q_1+q_2)=52\cdot (1+0.06+0.2)=65.52 \end{gathered}$$
