You buy three hamburgers and a soda for $14.20. If sodas cost $2.95, what is the price of each hamburger?

3.75

Step-by-step explanation:

14.20-2.95=11.25÷3=3.75 per burger

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
