You are told the ages of Karen and David in terms of Michelle's age.
Let m = Michelle's age.
Michelle's age = m
Karen's age = m + 6
Michelle is two years younger than David, so David is two years older than Michelle.
David's age = m + 2
Add the ages and get 62.
m + m + 6 + m + 2 = 62
3m + 8 = 62
3m = 54
m = 18
Michelle is 18 years old
Karen is 6 years older, so she is 24 years old.
David is 2 years older than Michelle, so he is 20 years old.
Answer:
Step-by-step explanation:
3 (4 -6) = -8 is correct. The next step is to combine 4 and -6, obtaining
3(-2)
and this 3(-2) should equal -6, which is not the same as -8.
3(4 - 6) = 12 - 18, which differs from the student's solution. This is the reason for the wrong answer.
The answer is 32$ per gram. You just divide 160 by 5 to get the answer.
Hope that helps!!!
