When a number is increased by 5.5%, the result is 60. What is the original number to the nearest tenth?

56.9

Step-by-step explanation:

Let the original number be denoted by x.

We are informed that when the number is increased by 5.5%, the result is 60. This can be represented by:

x + (5.5% of x) = 60

x + (0.055 × x) = 60

x + 0.055x = 60

1.055x = 60

x = 60/1.055

x = 56.9

The original number is 56.9

you probably already have the answer but anyways it's b. 15.0
