Which equation represents this sentence
“Mark is five years older than Jeffrey. The sum of Mark’s age and triple Jeffrey’s age is 73”

Answer 1

C

Explanation:

Let m represent Mark's age and j represent Jeffrey's age.

Mark is five years older than Jeffrey. Hence:

`m=j+5`

The sum of Mark's age and triple Jeffrey's age is 73. In other words:

`m+3j=73`

We can substitute:

`(j+5)+3j=73`

Therefore, our answer is C.
