Tom has a collection of 27 CDs and Nita has a collection of 18 CDs. Tom is adding 3 CDs a month to his collection while Nita is adding 6 CDs a month to her collection. Write and graph a system to find the number of months after which they will have the same number of CDs. Let x represent the number of months and y the number of CDs.
We have given,
Number of CDs collected by Tom = 27 CDs
Number of CDs collected by Nita = 18 CDs
Let the x represent the number of month and y represent the number of CDs
Tom is adding 3 CDs a month to his collection while Nita is adding 6 CDs a month to her collection.
According to problem, we can make equations as:
For Tom, total number of CDs , y = 27 + 3x
For Nita, total number of CDs , y = 18 + 6x
We need to find number of month when number of Tom’s CDs collection is equal to Nita’s CDs collection
