Answer: x = 0.22 cents
Step-by-step explanation: This is my first time trying to help someone so if I get something wrong I AM SO SORRY!!!!
First, find the unit rate of both companies.
To find company A's unit rate find what is the numerator and denominator. This is 65/13. We want a unit rate where 1 is in the denominator, so we divide the top and bottom by 13:
65 cents / 13
--------------------
13 dollars / 13
Divide both by 13 and you get 5 cents per dollar.
Now find company B's unit rate. Find the numerator and denominator, 11/40.50. Now this time we want 1 where the denominator is again. So we divide the top and bottom by 40.5.
11 cents ÷ 40.5
----------------------------------
40.5 dollars ÷ 40.5
Divide by 40.5 and you get 0.271605 cents per dollar. Round to the hundreths and get 0.27 cents per dollar
Now time to find how much company A charges more than company B. subtract 0.27 by 0.05 and you have your answer! x = 0.22 cents
