Answer:
A. 10%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
The new number is the increased wage, $8.25, and the old number is the original wage, $7.50.
percent change = ($8.25 - $7.50)/($7.50) * 100%
percent change = ($0.75)/($7.50) * 100%
percent change = 0.1 * 100%
percent change = 10%
Since the percent change is a positive number, it is a percent increase.
The percent increase was 10%.
Answer: A. 10%
Answer:
-10x + 1.5
Step-by-step explanation:
You can multiply 6.25 by 2 (which is 12.5) to find how much money he had before he bought the sandwich. Then you can find how much money he had before buying the DvD by multiplying 12.5 by 8/3 which is 33.33 dollars. Therefore Jake started with 33.33 dollars.
(you can prove this since 3/8 of 33.33 is 12.5 and 1/2 of that is 6.25)
I hope this helps. Let me know in the comments if anything is unclear.
