Acustomer paid 5$ in tax. his tax rate was 5%. fin the dollar amount of his purchase

Hey there!

Let's create an equation for this scenario.

0.05x=5

This equation shows that the $5 is equal to 0.05% (sales tax) of the cost paid for the item.

let's solve by dividing both sides by 0.05x.

x=100

Therefore, his purchase costed $100 before sales tax.

I hope this helps!

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
