submit answer

Explanation:

Step1: Determine the discount rate

The discount is 1%, which is \( 0.01 \) in decimal form. So the amount paid after discount is \( 100\% - 1\% = 99\% \) of the original cost.

Step2: Convert the percentage to decimal

\( 99\% \) in decimal form is \( 0.99 \). So the cost after discount is \( 0.99c \).

Answer:

0.99c
