Elena bought 8 tokens for $4.40. At this rate: 1)How many tokens could she buy with $6.05? 2) How much do 19 tokens cost?

She could buy 11 tokens and 19 tokens cost 10.45

Step-by-step explanation:

divide how much money you spent by how many tokens you bought

4.40/8=0.55 x 19= 10.45

6.05/0.55=11

answer:      

step-by-step explanation:

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
