Logan made a profit of 210 as a mobile groomer. he charged 75 per appointment and received 35 in tips but also had to pay a rental fee for the truck at 10 per appointment write an equation to represent this situation
explain how the equations from part pand part b differ

step-by-step explanation:

income: 75 * number of appointments + 35

costs: 10 * number of appointments

formula:

profit = income - costs = 75 * number of appointments + 35 - 10 * number of appointments

number of appointments * (75 - 10) + 35 =

65 * number of appointments + 35

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
