Answer:
A computer costs $225 and a printer $150.
Step-by-step explanation:
Let c be the cost of a computer and p the cost of a printer, then:
3c + p = 825
4c + 2p = 1200
Multiply the first equation by -2:
-6c - 2p = -1650
Add this to the second equation:
-2c = -450
c = 225.
Now substitute c = 225 in the first equation:
3*225 + p = 825
p = 825 - 675 = 150.
