Alex is using Cell Company A who charges a monthly fee of $20 in addition to $1.50 per GB of data. Haley is using Cell
Company B who charges a monthly fee of $15, but charges
$3.00 per Gigabyte of data. If d represents the amount of
data, figure out how many Gigabytes of data both Alex and
Haley would have to use for their cell phone companies to
charge them the same amount. Only an algebraic solution
will be accepted.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

11

step-by-step explanation:

32.50-7.50=25

225/25=11

ou would have 12 of each
