Answer:
C.
f(x) = 0.34 + 0.21(x – 1); $.97
Step-by-step explanation:
In 2002, the price of mailing a letter was $.34 for the first ounce and $.21 for each ounce after the first ounce. Write a rule to describe the function.
---------------------------------------
Price = 0.34 + 0.21(x-1) where x is the weight of the item in ounces.
Let +x+ = weight of the letter in ounces
Let +P+ = the price of mailing the letter in dollars
---------------------------------------
+P+=+.34+%2B+.21%2A%28+x+-+1+%29+
( +x+%3E=+1+ )
-----------------------------
A 4-ounce letter costs
+P+=+.34+%2B++%28+4+-+1+%29%2A.21+
+P+=+.34+%2B+.63+
+P+=+.97+
It costs $.97
1. Yes, because it can be written as a fraction.

Answer: x(.25)+(4+x(.25))=y
Step-by-step explanation:
1. set up the equation-
Ali has an unknown amount of quarters so make that x.
We know quarters are 25 cents so .25 if he has one quarter you put that one quarter into x, 2 into x and so on
Tom has 4 more, since he has 4 more it is 4+x and one again times .25
2. that is it
