This is a linear equation in slope intercept form
where
the slope is
----> the coordinate y of y-intercept
To find out the cost of 10 balls, substitute the value of n=10 in the linear equation and solve for P
so
For n=10
= 4018 is the answer
12
just divide 7 1/5 ÷ 3 over 5 = 180/15
and that simplified is 12
