It might be f but I’m getting a positive 6 instead of a negative
Answer:
105
Explanation:
Adding 5% of 100, to 100 is:
100(0.05) + 100
The extra 100 is added because 100(0.05) only gives you what 5% of 100 is.
10% of 26.80 = 2.68
5% of 2.68 = 1.34
2.68 + 1.34 = 4.02
Your best estimate is 4.05
As a fraction it would be 13/52
As a percent it would be 25%
