Answer:
The cost of the lessons taken
Explanation:
Let
y -----> the total paid for the baseball bat and the lessons
c ----> the number of lessons
we have
y=25c+75
This is a linear equation in slope intercept form
y=mx+b
where
b=$75 -----> the price of he baseball bat (y-intercept)
m=25 $/lesson ----> the slope of the linear equation
therefore
25c represent the cost of the lessons taken
