Molly and henry went shopping for books molly bought 7 books for $42 and henry bought 8 book for $52 who got the better buy Explain and show work

Molly

Step-by-step explanation:

because molly had

42 divided by 7  

that gave her 6$ per book.

But Henry has

52 divided by 8

which is about 6.5.

That's why molly got the better deal.

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

faster, im not sure why but i know it is faster
