one number is 30% more than another number. their sum is 23. what are the two numbers

Question

x+x+30+=

 

Answer 1

Let one number = x

Let the other number = x + 0.30x

 

Set an equation to represent the sum of these numbers.

 

x + x + 0.30x = 23

 

 

Solve for x.

 

2.30x = 23

 

 

Divide both sides of the equation by 2.30.

 

x = 10

 

 

This means that one number is 10 and the other number is

 

10 + 0.30(10) = 10 + 3 = 13
