Question

A doctor’s office schedules 15-minute appointments and half-hour appointments for weekdays. The doctor limits these appointments to, at most, 30 hours per week. Write an inequality to represent the number of 15-minute appointments x and the number of half-hour appointments y the doctor may have in a week.

Answer 1

x = number of 15-minute appts
y = number of 30-min appts

x*(1/4) + y*(1/2) <= 30 hours, because doc doesn't want to work too hard

That's it! :)
