1. Ivan bought three magazines for $6.50 each. The sales tax was 7%. What was the total amount that Ivan paid for the magazines?

I got 6.955

I would round and say he paid $6.96

Step-by-step explanation:

i multiplied 6.50 by 1.07

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
