Answer:
The equation needed is 
The cost per ream of paper = $4
Step-by-step explanation:
Here, the cost of 5 reams of paper = $ 21
The tax on her purchase = $1
So, the actual cost of 5 reams of paper = Total Cost paid - Tax amount
= $ 21 - $ 1 = $20
So, the actual cost of 5 reams of the paper is $20.
Now, to find out the cost of 1 ream of paper:

= $4
Hence, the cost of each ream of paper = $ 4.

Answer:
f(x)=-2x+9
f(4)+3=?
let x equal to 4
f(4)=-2(4)+8
f(4)=-8+9=+1
f(4)=1
then add 3 to f(4)
f(4)+3=1+3
f(4)+3=4
and he need f(4)+3 so the answer is
4
that's it
