Answer:
OKay so this question is actually <em>UNCLEAR</em>.
Do they mean how many <em>more</em> days <em>until</em> they have enough money, or how many days in <em>GENERAL</em> until they have enough money (excluding the money Jimmy already saved, $40)?
Assuming the former, <u>the answer should be 30 days. </u>
Step-by-step explanation:
Since Jimmy has $40 already currently, he'd need to make 60 more dollars, right? So since our boy Jimmy makes 2 dollars a day, multiply that by 30 and that'd equal 60. So the answer should be 30 more days until Jimmy has enough money for his trip.
