first problem 28, second problem 72
________________________________________________________
If Kelly's mom is 35, it will take her 15 more years to become 50. Make an equation to represent this.
[tex]35 + 15 = 50[/tex]
Next, you want to add 15 to Kelly's age because for each year her mom ages, she ages for that same number of years.
[tex]13 + 15 = 28[/tex]
________________________________________________________
For the second problem, we just do an inverse of the problem. If Kelly is 13 and her mom is 35, how long will it take Kelly to become 50? How old will her mom be?
It would take Kelly 37 more years to become 50, because 37 + 13 = 50
Now that we have found the number of years remaining, add her mother's age by the remaining years left, r
[tex]35 + r(37) = 72[/tex]
