b. Write an equation for the total income I for n bikers.

c. Write an equation for the profit P for n bikers

Answer 1

Answer: a. The equation for the total expenses E for n bikers is:

E = 30n + 125n + 700

b. The equation for the total income I for n bikers is:

I = 350n

c. The equation for the profit P for n bikers is:

P = I - E = 350n - (30n + 125n + 700) = 195n - 700
