Answer:
3p + 8n,    12p + 2n,    9p+4n,    6p+6n
8 columns bar graph.
Step-by-step explanation:
$2 = pen
$3 = notebook
This could be written as a bar graph in multiples of $6.00 along y axes.
3 pens + 8 notebooks. Then 12 pens + 2 notebooks.
Then 9 pens + 4 notebooks . Then 6 pens + 6 notebooks 
3p + 8n,    12p + 2n,    9p+4n,    6p + 6n
3p = $6
8n = $24
12p = $24
2n = $6
9p = $18
4n = $12
6p = $12
6n = $18
and so on... 
 
        
             
        
        
        
Answer: 8,7 
Step by step:
Because the numbers on the left sides are numbers that represent the y-axis which is how far up or down the point will be.
7 is the smallest number making it the closest to the x- axis.

Complementary angles add up to equal 90 degrees. Knowing this, you can subtract 68 from 90. 90-68=22.
Hope this helps.
