As a receptionist for a hospital, one of Elizabeth’s tasks is to schedule appointments. She allots 60 minutes for the first visit and 30 minutes for a follow-up. The doctor cannot perform more than seven follow-ups per day. The hospital has eight hours available for appointments. The first visit costs $120 and the follow-up costs $70. Let x be the number of first visit and y be the number of follow-ups.
 

 1. 
Write a system of inequalities to represent the number of first visits and the number of follow-ups that can be performed.
a.
60x + 30y mc001-1.jpg 480 and y mc001-2.jpg 7
x mc001-3.jpg 0 and y mc001-4.jpg 0
c.
30x + 60y mc001-9.jpg 420 and y mc001-10.jpg 7
x mc001-11.jpg 0 and y mc001-12.jpg 0
b.
60x – 30y mc001-5.jpg 480 and y mc001-6.jpg 7
x mc001-7.jpg 0 and y mc001-8.jpg 0
d.
60x + 30y mc001-13.jpg 420 and y mc001-14.jpg 7
x mc001-15.jpg 0 and y mc001-16.jpg 0
 

 2.

d.
mc002-4.jpg
 

 3.

c.
(0, 0), (7, 0), (4.5, 8), (0, 8)
b.

c.
8 first visits and 0 follow-ups
b.
4 first visits and 8 follow-ups
d.
4 first visits and 7 follow-ups
