What is the percentage increase in candy bar price. We need to know the original price and the amount by which price is increased to find percent increase.
Let's look at statements.
(1) The price of the candy bar was increased by 5 cents. Not sufficient as only the increase is given.
(2) The price of the candy bar after the increase was 45 cents Not sufficient as only the final price is given but original price cannot be determined.
(1)+(2) : Sufficient as both original price and price increase can be determined and hence the percent increase
Hence Option (C) is our choice.
Best,
G

Statement 1:
Only gives info about the increase in price. So insufficient to determine the percentage price increase.
Statement 2:
After increase price became 45 cents. But how much was it increased? No info.
Insufficient.
Combining both:
45-5 = 40 Cents was the original price.
Percent Increase = 5/40 = 12.5%.
C is the answer.
