The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a price tag
Step2247 [10]

Answer:

$96.15

Step-by-step explanation:

Given data

markup = 30%

cost price= $125

let the cost price before markup be x

125-30/100*x= x

125-0.3x= x

125= x+0.3x

125= 1.3x

divide both sides by 1.3

x= 125/1.3

x= $96.15

Hence the price before markup is $96.15

Can someone help me find the value of z? ⅔z + 1 = 13
sergey [27]

Answer:

z = 18

Step-by-step explanation:

Given: ⅔z + 1 = 13

Subtract one from both sides: ⅔z = 12

Multiply both sides by the inverse of 2/3, which is 3/2: z = 18

Have a nice day!

What is the x-intercept for the following linear equation:
Alexandra [31]
The "x-intercept" occurs when y=0, because it is at this point that the equation touches the x axis.  So if you plug in y=0 into the equation you can solve for the x coordinate.

4x-2(0)-8=0

4x-8=0

4x=8

x=2

So the x-intercept is the point (2,0)
