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?​

Respuesta :

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
