Given:
Machine A Candy Packing
x(minutes) y(candies)
5 600
10 1200
15 1800
20 2400
Machine B : y = 150x
Find number of candies packed in 12 minutes.
Machine A : 600/5mins = 120 candies per minute
120 * 12 minutes = 1,440 candies
Machine B : y = 150x ⇒ y = 150(12) ⇒ y = 1,800
Machine B: 1,800
Machine A: 1,440
Difference 360
Machine B packed 360 more candies than Machine A in 12 minutes.
