Chapter 7.6, Problem 18E

To determine

To find: The total amount of money paid by the dog owner.

Answer to Problem 18E

The total amount of money paid by the dog owner is $\$22$ .

Explanation of Solution

Given information: A dog owner pays you $\$20$ plus a $10\%$ tip for walking a dog.

Calculation: The amount of money paid by the dog owner for walking the dog- $\$20$ , and The tip- $10\%$ .

The amount of tip = The paid amount $\times$ Rate of the tip

  $\begin{array}{l}=\$20\times 10\%\\ =\$20\times \frac{10}{100}\\ =\$20\times 0.10\\ =\$2\end{array}$

The amount of the tip should be added with the paid amount.

Let’s find the total paid amount,

  $\begin{array}{l}=\$20+\$2\\ =\$22\end{array}$

Hence, The total amount of money paid by the dog owner is $\$22$ .
