3. Teammates Mark and Jonas are discussing the outcome of a game.
Mark says their team scored 500% as many goals as the other
team and Jonas says they scored ﬁve times as many goals as the
other team. Can they both be correct? Explain how you know.
Say the score is 3-15. If the team Mark and Jonas are talking
about is 15, then they would both be correct, because 3x5=15, the team with 15 would be ahead 5 times as many goals than the other team.
