Matt's father is 4 times as old as matt. If the sum of their ages in NO LESS THAN 75, what is the youngest Matt can be?

1 answer

Let Matt's age be represented as M. Therefore, Matt's father's age will be 4M.

The sum of their ages can be written as: M+4M=5M

We know that this sum must be no less than 75, which gives us the inequality: 5M75

To find the minimum age for Matt, we can divide both sides of the inequality by 5: M755 M15

Therefore, the youngest Matt can be is 15.
