Profit = revenue - expenses

P = 5c - 39 <== ur equation
x < = 40

ur independent variable is c, the number of cars
ur dependent variable is p, ur profit

yes, this relationship is a function because for each value of c there is a unique value of p

ur domain (ur c values) will be : 0 < = c < = 40
ur range (ur p values) will be -39 < = p < = 161
