Question

A hospital parking lot charges ?$2.50 for the first hour or part? thereof, and ?$1.25 for each additional hour or part thereof. A weekly pass costs ?$39.00 and allows unlimited parking for 7 days. If each visit Jonny makes to the hospital lasts three and a half? hours, what is the minimum number of visits for which buying a pass would be less expensive than paying each? time?

Answer 1

The daily charge is $2.50 for the first hour

then $1.25 for each additional hour or part therefo

 

So, 3.5 hours means $2.50 (first hour) + $2.50 (second and third hour) + $1.25 (for 1/2 hour) for a total of $6.25

 

so $39.00 ÷ $6.25 = 6.24

 

any number of visits above  6 will be less costly if a weekly pass is purchased
