Answer:

Step-by-step explanation:

Let the missing value of y in the table be a.

Since, the slope of the line through the ordered pairs (1, 3), (2, a) is 4.

$slope = \frac{a - 3}{2 - 1} \\ \\ 4 = \frac{a - 3}{1} \\ \\ 4 = a - 3 \\ \\ 4 + 3 = a \\ \\ a = 7$

Thus, the missing value of y in the table is 7

An office supply company orders packs of pens for two of its stores. For the first store, the order is for 60 packs of ballpoint

AlekseyPX

Answer:

Option A. The cost of one pack of ballpoint pens is $3 and the cost of one pack of gel pens is $7.

Step-by-step explanation:

Let

x -----> the cost of one pack of ballpoint pens

y -----> the cost of one pack of gel pens

we know that

60x+25y=355 -----> equation A

120x+30y=570 -----> equation B

Solve the system of equations by graphing

Remember that the solution of the system is the intersection point both graphs

The solution is the point (3,7)

see the attached figure

therefore

The cost of one pack of ballpoint pens is $3

The cost of one pack of gel pens is $7
