Yes you have a good example.
x = number of cookies
2*x = total amount spent on cookies at $2 each
2x-3 = amount you pay after the $3 discount is applied one time for the entire order
-------------
a more numeric example may be this
Lets say you bought 12 cookies, so x = 12
This means it costs 2*x = 2*12 = 24 dollars total if the discount doesnt apply
However, the 3 dollar discount is there, so the grand total is 24-3 = 21 dollars.
First you have to find the like terms
3xy + 10xy - 2xy and -5x + 2x
After that you solve for the like terms to find the final answer
11xy-3x
A.) The insurance company's payment is 80% of the total minus the $500 deductible, so:
(10000 - 500) * .8 = 7600
B.) To find the Copay, you do almost the same thing:
(10000 - 500) * .2 = 1900
C.) Mary's Total Cost: 1900 + 500 = 2400.00
Answer:
y = 31
Step-by-step explanation:
We'll, if x + y = 10,
and x = -21,
then: -21 + y = 10.
To solve, add 21 on both sides to get y = 31
