Together a computer, monitor, and printer cost $1935. the monitor cost $400 less than the computer, the printer cost $50 more than the monitor. Find the cost of the printer.

C: computer

m: monitor

p: printer

c+m+p=1935

m+400=c

p=m+50

substitute the last two equations into the first one:

m+400+m+50+m=1935

3m=1485

m=495

Substitute into the other equations

c=495+400=895

p=495+50=545
