The cost(y) of producing x number of balls is given by the linear model y = 3.25x + 685000
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Let y represent the cost of producing x number of beach balls.
Using the point (10000, 587500) and (50000, 717500):
