This is a proportion question.
Answer: Brandon is 24, Michael is 72.
Step-by-step explanation:
Let m represent Michael
Let b represent Brandon
Then,
m = 3b <-----------"Michael is 3 times as old as Brandon."
m - 18 = 9(b - 18) <-----------"18 years ago, Michael was 9 times as old as Brandon."
3b - 18 = 9b - 162
-18 = 6b - 162
144 = 6b
Michael is 3 times as old as Brandon. Also, 18 years ago, Brandon would have been 6 and Michael would have been 54 meaning Michael was 9 times as old as Brandon 18 years ago.
15 is the answer because 5 is a prime factor so 5 into 105=21 and 3 is another prime factor so 3 into 21=7 and 7 is another so 7 into 7=1 and 5+3+7=15
