Greetings!</h2>
If x = the first number (equal to 1x) then the second number is 75% more than this.
This means the value of the bigger number is 100 + 75 (because 100 is the starting number and 75 is the percent bigger)
This can be shown with the following equation:
Amount * 
x *
= 1.75x
1.75x is the value of the bigger number.
