Answer:
30
Step-by-step explanation:
We need to find the number, which, when increased by 130% equals to 69
It can be written as following equation if we call the number x:
- x + 130% of x = 69
- x + x*1.3 = 69 ========= 130% of x equals to 1.3 x
- x (1+1.3) = 69
- 2.3x = 69
- x = 69/2.3
- x = 30
So the answer is 30
