Apair of shoes costs $52.99 and the state sales tax is 8%. 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.$57.23

b.$60.99

c.$95.38

d.$78.19

A The pair of shoes costs $52.99, so p = 52.99.
The state sales tax is 8%, which can be changed to decimal form by dividing by 100: 8/100 = 0.08. So r = 0.08.
Now you can plug both of these values into the formula to find the total cost of the shoes (c):

c = p + r*p
c = 52.99 + (0.08)*(52.99)
c = 52.99 + 4.2392
c = 57.2292
So the total cost of the shoes is $57.23.
