X=25
4x-10=90
Add 10 to both sides
4x=100
Divide both sides by 4
Y = -3x + b
Plug in points
4 = -3(-2) + b
4 = 6 + b, b = -2
Solution: y = -3x - 2
2 because rise/run so 8/4 which=2
Answer:
$54
Step-by-step explanation:
Price of jacket = $75
Markdown = 33.33...%
Sales tax = 8%
First we have to find the price of the jacket after the markdown.
75-33.33(75)
75-(25)
50
New price of jacket = $50
Now to calculate the price with sales tax.
50+0.08(50)
50+(4)
54
