Question
A long-distance phone call costs $0.55 for the first minute and $0.09 for each additional minute or portion thereof. Write an inequality representing the number of minutes a person could talk without exceeding $7.
Wouldn't that just be
9t + 55 ≤ 700
where t is time in whole minutes?

Yes that is correct.
You moved the decimal over twice for all of the numbers, and the equation would be 9t + 55= ? (=? would be < 700)
