Question

In x years from now, Robert will be k

years old. How old was Robert m
years ago?
A) x-(k+m)
B) k-x
C) k-x-m
D) x-(k-m)

Answer 1

I think the answer would be C, because

Explanation:

Example:

If in 6(x) years Robert is 16(k), how old was he 3(m) years ago?

First, you would have to find out how old Robert is now, 16-6=10

Then, you would take 10, his current age, and subtract 3(m) 10-3=7

I hope this helped, good luck!

Answer 2

Since Robert will be
`k` years old in
`x` years, he must be
`(k-x)` years old now.

• 
  `Robert=(k-x)old`

Robert was
`(k-x)-m` years old;
`m` years ago.

• 
  `Robert=(k-x)-m`

The answer is C.
