M= 1/2x+6
N= 1/2x-3

Answer:
3 bulbs should be flawed
Step-by-step explanation:
2+ 18 = 20
20 bulbs were examined
2/20 = 1/10 were flawed
looking at the next 30 bulbs
30 * 1/10 = 3
3 of the next 30 bulbs should be flawed
Breaking the it down- simplifying
0/2=0 because anything divided by zero is zero.
13.25x3-(8.50x3)=x x is the cost of the system
