Answer:
12 machines
Step-by-step explanation:
The production rate per machine is 1240/20 = 62
For 1,984 printers it would take 32 machines (1984/62 = 32)
32 needed minus the 20 they already have means they need 12 more machines.
I think the answer is 126.6466666666667but rounded be 126.65
-14.5
Basically, -(7.5+4) is -11.5 and then combine -3 with -11.5 which yields -14.5
