Question

Wesley and Jim both work out at the gym. Wesley weighs 132 pounds and is gaining 7 pounds each month. Jim weighs 150 pounds and is gaining 4 pounds each month. How many months will it take for Wesley to weigh the same as Jim?

Answer 1

The number of months that it will take for Wesley to get to the same weight as Jim, given their respective weights, is 6 months

How to find the number of months?

Assuming the number of months is denoted by x, the equation to find Wesley's weight in a given month would be:

= Wesley's current weight + ( 7 x number of months)
= 132 +  7x

This means that Jim's weight would then be:
= 150 + 4 x

This means that the month where both of them will have the same weight would be:

132 + 7x = 150 + 4x

7x - 4x = 150 - 132

3x = 18

x = 18 / 3

x = 6 months
