Question

2. Daniel paid $22 for a water bottle. This amount includes 5% tax. What was the cost of the item before tax?

Answer 1

Answer:

$20.9

Step-by-step explanation:

100%=22

95%=x

95x22=2090/100=20.9

Answer 2

Answer:

$20.95 (rounded)

Step-by-step explanation:

To solve this, you need to first make an equation where x is the original cost before tax. So it would be 22=1.05x. You know it is 1.05 because 1 is the "whole" original cost and 0.05 is the 5% tax in decimal form. To solve the equation, you divide both sides by 1.05 to get x=20.95
