Math Problem!?
To rent an apartment, a one-time deposit is frequently required with the first month's rent. Roberto paid $900 the first month and a total of $6950 during the first year. Find the monthly rent and the amount of deposit.
All I really need to know is how to set it up if you don't want to do the whole problem. Thanks if you can help me.

to find out how much he paid on a monthly basis.
(6950 - 900)/11=550
The monthly rent is $550 and the deposit is $350
A deposit is usually the same as the first month's rent, so subtract 900 from 6950 and divide that number by 12 to give you the monthly rent.
Let x = the deposit paid
Let y = the monthly rent
x + y = 900 (equation 1)
x + 12y = 6950 (equation 2)
Then rearrange either equation (to the form "x = ...") and substitute into the other equation.
(x+y) + 11Xy=6950
x+y=900
y = rent
x = deposit
900+ 11y = 6950
11y = 6950-900
y=6050/11
900-r=d
900+11r=6950
d=deposit
r=rent
i think. . .
r=550
d=350
