Question

Adam's age is 6 years less than one-third of Melissa's age. Adam's age is 18. How old is Melissa?

A. 12
B. 72
C. 36
D. 78

Answer 1

B. 72

Explanation:

Adam (A): 18

Melissa (M):?

`A=(m)/(3) -6`

`18=(m)/(3) -6`

`24=(m)/(3)`

`m=4(3)=72`

Therefore, Melissa is 72 years old.

Hope this helps!

Answer 2

what's up? this answer is B, 72

we can figure out that one third of melissa's age is 24 because 18+6= 24. simply eliminate the obvious incorrect answers, A and C. 78/3= 26 so it isn't D
72/3=24 it is B
