Question 269381: Please help solve not understanding it.
A hospital parking lot charges $2.00 for the first hour or part thereof, and $1.00 for each additional hour or part thereof. A weekly pass costs $47.00 and allows unlimited parking for 7 days. If each visit Johnny makes to the hospital lasts two and a half hours, what is the minimum number of visits that would make it worthwhile to buy a pass?
Answer by edjones(8007) (Show Source): You can put this solution on YOUR website!
each visit costs Johnny 2+((2.5-1)/2)=2+(1.5/.5)=$5
Let x=number of visits required to be worthwhile. In this case x must be an integer.
5x>=47
x>=9.4
x=10 minimum number of visits that would make it worthwhile to buy a pass.
