Question

When 80% of a number is added to the number the result is 180

Answer 1

n = 100

Explanation:

We can let n represent the number we're trying to find.

Taking 80% of a number is the same as multiplying the number by 80/100 or 0.80.

Thus, we can use the following equation to find the number:

`n+0.80n=180\\1.80n=180\\n=100`

80% of "100" is 80.

80 "added to" 100 is 180
