An item is purchased for a wholesale price of $48 and will be sold at a 55 percent markup. which expression should be used to find the amount of the markup?

The answer is 48(0.55) x 48

The answer is 48(0.55) x 48

Step-by-step explanation:

wholesale $48 and sold at 55% which is the same as 0.55 then multiply wholesale by percent

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
