One number is 5 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 296​, find the numbers.

Answer 1

Let the first number = x

The second number would be 5x

The third number would be 100x

Add:

X + 5x + 100+x = 296

Simplify:

7x + 100 = 296

subtract 100 from both sides:

7x = 196

Divide both sides by 7

X = 196 / 7

X = 28

First number is 28

Second number is 28 x 5 = 140

Third number = 128
