Samuel paid $9.10, including tax, for a dog collar. before tax, the original price of the collar was $8.75. what was the sales tax rate? let r represent the rate as a decimal. complete the equation that represents the problem. (hint: the original price of the collar plus the amount of tax equals the total cost including tax.)

r=0.04

Step-by-step explanation:

The original Price of the Collar= $8.75

Amount Paid by Samuel =$9.10

Tax Paid = Amount Paid- Original Price

               =9.10-8.75=$0.35

Let x be the rate of tax.

The rate is 4%.

Therefore, rate of tax(r) in decimal = 0.04.

NOTE: Since the equation to be completed is not given, I have simply found the rate and hope you can pick it up from there.
