show all work.

a) $87.12
b) $92.93
c) $100.60
d) $145.20

$87.12

Step-by-step explanation:

Tax: 8%

20% as a tip

First, we must add the tip to how much she was charged.

72.6 x 0.2 = 14.52 72.6 + 14.52 = $87.12

The tax doesn't count because it only asks for the service at the salon.

I hope this helped!

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
