The following graph shows the relationship between cost and revenue for a manufacturer of lab coats.

i - cost: 1.5n+1,600
ii - cost: 4.5n+1,600
iii - revenue: 3.25
iv - revenue: 5.75

which of the following pairs of equations best suits this graph?

a.
i and iii

b.
i and iv

c.
ii and iii

d.
ii and iv

Option a.

I and III

Step-by-step explanation:

Observing the graph

For n=400 coats

The cost is about $2,200

and

The revenue is less than $1,400

Substitute the value of n=400 in each equation to find the solution

I Cost 1.5(400)+1,600=$2,200 > is ok

II Cost 4.5(400)+1,600=$3,400 > is not ok ( is greater than $2,200)

III Revenue 3.25(400)=$1,300 > is ok ( is less than $1,400)

IV Revenue 5.75(400)=$2,300 > is not ok ( is greater than $1,400)

therefore

The solution is I and III

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.

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
