PLEASE HELP! What is the price of 8 notebooks and 7 pens if 4 notebooks and 3 pens cost $96, while 2 pens and 2 notebooks cost $54?

$204

Step-by-step explanation:

Create a system of equations where p is the price of a pen and n is the cost of a notebook:

4n + 3p = 96

2n + 2p = 54

Solve by elimination by multiplying the bottom equation by -2:

4n + 3p = 96

-4n - 4p = -108

-p = -12

p = 12

So, a pen costs $12. Plug this in as p into one of the equations, and solve for n:

2n + 2p = 54

2n + 2(12) = 54

2n + 24 = 54

2n = 30

n = 15

So, a notebook costs $15.

Using this, find the price of 8 notebooks:

15(8)

= 120

Find the price of 7 pens:

12(7)

= 84

Add this together:

120 + 84

= 204

So, the price of 8 notebooks and 7 pens is $204
