Brownies are $1.58 for a 6-pack

brownies are $3.99 for a 12-pack
which is the better buy per a brownie?

Step-by-step explanation:

First you divide 1.58 and 6 to find how much one brownie is.

So that would be roughly $0.26.

Now you divide 3.99 and 12 which is roughly $0.33.

So you now have to see which one has a smaller cost. Which is $0.26. SO it would be the 6-pack.

Another way to figure is out to multiply 0.26 and 12, and 0.33 and 6.

0.33 x 6=1.98

0.26 x 12=3.12

So that makes it more clear that the 6 pack is a better buy!

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
