Here is a word problem that I have been working on for the past 2 days. I have a very hard time with these type of problems so will you please look at my work and see if I am anywhere near being correct?
Problem: A hospital parking lot charges $4.00 per hour for the first hour or part thereof, and $2.00 for each additional hour or part thereof. A weekly pass costs $38.00 and allows unlimited parking for 7 days. If each visit Jonny makes to the hospital last two and one-half hours, what is the minimum numer of visits that would make it worthwhile to buy a pass?
I said 15.2 hours
here is my work: with h for hour and d for dollars I did the following: ( this was the best of all I did)
38d divided by 2.5h = 15.2h
4d + 2.5h = 8d divided by 38d =4.75d = 60.8
60.8d - 38d = 22.8d which is the amount Jonny would save in a month by buying a pass.
Actually should the answer be 0? Because if Jonny buys a monthly pass for $38.00 he will have unlimited parking for 7 days out of that month?
I am really confused and would appreciate any help I can get.
Thank you,
Cyndi
