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
The cost of the printer will be $545
We have the sum total of costs of computer, monitor and printer equal to $1935.
We have to find the cost of the printer.
We have -
x + y = n and y = 2x
Therefore -
x + 2x = n
3x = n
x = @@MATH_TOKEN_0@@
In the question given -
Let us assume that the cost of computer be x.
Then,
the cost of monitor will be = x - 400
the cost of printer will be = x - 400 + 50 = x - 350
Then, According to question -
x + x - 400 + x - 350 = 1935
3x - 750 = 1935
3x = 1935 + 750
3x = 2685
x = 895
Cost of Printer = 895 - 350 = 545
Hence, the cost of the printer will be $545
