Roberto bought a new recliner. He was able to pay $200 at the time he received the recliner. He wiil pay $20 each moth on the balance. The original cost of the recliner was $400. a. Let x represent the number of months needed to pay off the cost of the recliner . Explain how the equation 200 + 20x = 400 represents this situation.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

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

the answer is 5/14.

hope this .
