A retailer buys jackets at a cost of
$24 each and sells them at a 175%
increase in price. What is the retail
price of a jacket?

$66

Step-by-step explanation:

Using the formula for percent increase in price, we get:

So, the retail price of the jacket is $66.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
