Respuesta :

If all orders are identical, and you want to use all the bulbs,

 you have to divide all three types of bulbs into the same

 number of groups, meaning you have to find the greatest

common factor, which is 8. So you get for each order 8 of

the 60W, 6 of the 75W, and 7 of the 100W; making 8 orders
