Answer:
Jennifer used $24-14=10 dollars in total.
The $10 was spend on five pens, each pen costing say, x, dollars.
The equation would be 10 = 5x
x = 10÷5= $2
So each pen costs $2 :)

Y=2 yes (the slope is 0 and the y intercept is 2)
8n−7y−12n+5−3y
=8n+−7y+−12n+5+−3y
Combine Like Terms:
=8n+−7y+−12n+5+−3y
=(8n+−12n)+(−7y+−3y)+(5)
=−4n+−10y+5
