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?
Let A unit be a; B unit be b
a + b = 95
b = 95 - a
3a + 5b = 395
3a + 5(95 -a) = 395
3a + 475 - 5a = 395
-2a = -80
a = 40
a + b = 95
40 + b = 95
b = 55
Therefore, a = 40; b = 55.
Hope this helps
