First step you would have to do would be to times 35 by 12 to see how much you would have to pay for 12 months.
35 x 12 = 420
Then, as you said, you a down payment of 600 so then you'd add.
600 + 420 = 1,020.
So the total cost of the computer would be $1,020.
........................................... i dont know, i dont remember doing this
231 / 385 = 0.6 diving the price it is by the price is was gives the answer
= 60%
12y = - 2x - 1
y = - 1/6x - 1/12
- 1/6 × m2 = - 1
m2 = 6
9 = 6(0) + c
c = 9
y = 6x + 9
The inverse function is 1.3*1.46^t
