The formula to find the final amount A, compounded yearly for x year at r% when p is the initial amount :

[tex] A=p(1+r)^x [/tex]

Given that, $1000 is deposited into an account that earns 5% interest.

So, p = 1000 and r =5% = 5/100= 0.05.

Next step is to plug in these values in the above equation to get the equation.

Hence,

[tex] A = 1000(1+0.05)^x [/tex]

=[tex] 1000(1.05)^x [/tex]

So, the correct choice is C) y=1000(1.05)^x.

Hope this helps you!
