is my answer correct and did i put this sign: > correctly in my equation, please check, thanks

Answer 1

Since we are talking about costs, a better deal is a lower cost, so the inequality should read:
.80x + 29 < 1.19x + 17
The answer is <i>almost</i> perfect...
30.769 rounds to 30.8, although in this case, it does not count because we are talking about integers.
