Question

A pair of shoes costs $30.99 and the state sales tax is 5%. Use the formula C = p + rp to find the total cost of the shoes, where C is the total cost, p is the price, and r is the sales tax rate.. .A. $46.49. B. $35.99. C. $41.24. D. $32.54

Answer 1

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.

Answer 2

Answer:

d.$32.54 is the answer

Step-by-step 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
