Answer:

d.$32.54 is the answer

Explanation:

First, write the rate as a decimal by moving the decimal point two places to the left from the percent.

r = 5% = 0.05

C = p + rp

C = 30.99 + 0.05 * 30.99

C = 30.99 + 1.55

C = 32.54

Answer: The total cost is $32.54

*hope this helps*

Here is the solution of the given problem above.
Given: Cost (C) = $30.99
Tax (r) = 5%
Formula: C = p + rp
So, C = 30.99 + (0.05)(30.99)
C = 30.99 + 1.5495
C = 32.5395
The total cost of the pair of shoes would be $32.5395. Round this off to the nearest tenths and the result is $32.54. Therefore, the correct answer would be option D.
