Explanation:
Drive through Full Service
Annual revenue 200,000 500,000
Cost 100,000 150,000
Income 100,000 350,000
Employee 5 15
Income / employee 20,000 23,333.33
Using simultaneous equation ,
Let X represent the drive through service ,and Y represent the full service restaurant
Budget = 100,000x + 150,000y ≤ 2,400,000 (equation 1)
Employer = 5x + 15y ≤ 210 (equation 2)
(Divide equation 1 by 10 ,000)
10x+ 15y ≤ 240 (equation 3)
Using elimination method, multiply equation 2 by -2
10x +15y ≤240
-10x - 30y ≤-420
-15y ≤ -180
y≤ -180/-15
y = 12
substitute y = 12 in equation 3
10x + 15y≤240
10x +180 ≤240
10x≤240-180
10x≤60
x≤6
12 1,800,000 180
6 600,000 30
6 drive through services and 12 full services should be opened.
6 Drive through 12 full service 20
