Say x is the number
7x +3 = 39 -2x
Add 2x to each side
9x +3 =39
Subtract 3 from each side
9x =36
Divide by 9 on each side
x=4

If the table is:
x | y
------
1 | 76
------
2 | 92
---------
3 | 108
-----------
4 | 124
-------------------------------------------------------------------------------------------------------------------
Find the change inbetween each amount per week
92 - 76 = 16
108 - 92 = 16
etc.
This means that her initial deposit should be subtracting 16 from her first deposit.
76 is the amount first deposited
76 - 16 = 60
A) $60 should be your answer
