A company has two separate offices. One office has a color printer and the other office has a black and white

printer. The number of pages printed daily on the color printer varies with Hc = 1800 and o c = 140. The

number of pages printed on the black and white printer varies with Mbw = 2000 and Obw = 250. Assume that

the numbers of pages printed by the offices are independent of each other.

Noe Alexander · Answer 1

the larger of two printers being used to print the payroll for a major corporation requres 40 min. to print the payroll. So the smaller printer's payroll printing rate is

1 payroll per x min or or

>> ... After both printers have been operating for 10 min, the larger printer malfunctions ... <<

So the fraction of the payroll that the larger printer did in the 10 minutes

is = payroll.
