The marked price of an electric iron was $36. During a sale, a discount of 12% was given. A further 7.5% discount was given
to those customers who bought more than one. How much
would a customer who bought three electric irons need to
pay for each electric iron? $

be more specific

step-by-step explanation:

heyyy

step-by-step explanation:

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

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
