Question

mario is 14 yrs younger than triple his grandfathers age. If mario is 8 yrs old, how old is his grandfather ( please explain) :)

Answer 1

3x-14 = 8

I suspect a typo. Is it reasonable for a kid to be almost 3 times as old as his grandfather?

Answer 2

I think he meant it the other way around

Answer 3

How is a grandfather 8?? that means that he had kids at 5 and his kids had grandkids at 4.... sooooo unless you're in Alabama that's illegal.

Answer 4

Ah, that makes sense. In that case, we'll reverse the equation:

Mario's grandfather's age = x
Mario's age = 8
Mario is 14 years younger than triple his grandfather's age, so:

3x - 14 = 8

Add 14 to both sides to isolate the variable:

3x = 22

Divide both sides by 3 to solve for x:

x = 7.33

Since we can't have a fraction of a year for an age, we usually round up or down to the nearest whole number. In this case, Mario's grandfather is either 7 or 8 years old - but since it's unlikely that someone would become a grandfather at age 7, we can safely assume that he's 8 years old.

Answer 5

Good catch! There must be an error in the problem statement. It is not possible for Mario to be 8 years old and for his grandfather to be 8 years old. We need more information to solve this problem correctly.
