Answer:
Jiri is 24 years old.
Step-by-step explanation:
Let "J" represent Jiri's age.
We could use "P" to represent Pamela's age, but that wouldn't help us in solving this problem.
However, we do know that Pamela's age is 3 times Jiri's age, so we can write Pamela's age to be 3J (3 times Jiri's age.)
We also know that the sum of their ages is 96.
Thus, we have: Jiri's Age + Pamela's Age = 96 years of age.
And: J + 3J = 96
Simplifying, we obtain: 4J = 96
Divide by 4 on both sides: J = 24
