there is a flat fee of 75.00, so start with that:
y = 75.00
Now, add .30 for each minute. For x minutes, that is .30x, so
y = 75.00 + 0.30x
No information is given on what happens after the first 1000 minutes, so all we can do is restrict the domain to what we know:
y = 75.00 + 0.30x for 0 <=x <= 1000
If the minutes after 1000 are free, then we don't need the restriction. If some other rate applies, we have to define y piecewise.
Jim pays $75 per month for a cell phone plan plus $0.30 per minute be on the first thousand minutes write an equation for the cause (y) based on the number of minutes(x)after the first 1000 I have become very confused.

Or, it occurs to me that maybe you have garbled the question, and it should read
$75 per month plus $0.30 per minute after the first thousand minutes
In that case, it's just
y = 75.00 for 0 <= x <= 1000
y = 75.00 + 0.30(x-1000) for x > 1000
$75 per month plus $0.30 per minute after the first thousand minutes
In that case, it's just
y = 75.00 for 0 <= x <= 1000
y = 75.00 + 0.30(x-1000) for x > 1000
