Problema Solution
A machine requires three hours to make a unit of Product A and five hours to make a unit of Product B. The machine operated for 395 hours producing a total of 95 units. How many units of Product B were produced?
Answer provided by our tutors
Total units 95 using product A and product B
A+B=95
A=95-B
time for A 3 hours
time for B 5 hours
total time 395 hours
3A+5B=395
3(95-B)+5B=395
285-3B+5B=395
2B=110
B=55
