Question

use c to represent the commission.
dollars
0% 20% 100%
349

Explanation:

Step1: Understand the relationship

The commission \( c \) is 20% of 349. To find 20% of a number, we convert the percentage to a decimal (20% = 0.20) and multiply by the number.

Step2: Set up the equation

The formula for commission (as a percentage of the total amount) is \( c = 0.20\times349 \).

Step3: Calculate the value

\( 0.20\times349 = 69.8 \)

Answer:

\( c = 69.8 \)
