16.5 because it would 165 divided by 10, so if you were to round it’s 17 because you can’t really get half a person.
There are 2 ways to do this. I'm going to do it the way that I think is most simple.
You have to find their LCM which is 40. Now times 40 to 1/4 v and 7/10
The equation then becomes 10+40v=28
You simplify it: 40v=18
v= 9/20
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
hope this helps
