The discount was 12 dollars off. You first subtract $530 from $650 & you'll be left with $120 . Then since it was you and 9 friends, that's a total of 10 people. So you divide 120 by 10 . Leaving you with the answer : $12 off which is the discount.
The answer would have to be C because he cannot sell negative hats or infinitely many because he only has 300 to sell in the first place. Answer choice D makes no sense because there is no value of x that is less than zero and greater than 500.
Hello from MrBillDoesMath!
Answer:
5, 10, 0
Discussion:
Let "f" be the first number. Then the questions tells us that
f + 2f + (f-5) = 15 =>
f + 2f + f - 5 = 15 => add 5 to both sides
4f = 5+ 15 = 20 => divide both sides by 4
f = 20/4 = 5
The numbers as
f: 5
2f: 10
(f-5): 0
Thank you,
MrB
