Answer:
the computer cost $712.50 and the printer cost $237.50
Step-by-step explanation:
cause $950 divided by 4 is $237.50 you can check the answer by doing 237.50 times 4
we have the two numbers, x and y
x - y = 3
y = 0.75x
x - 0.75x = 3
0.25x = 3
x = 12
We substitute x into an equation: y = 0.75x
0.75 x 12 = 9 so y = 9
They have a difference of three
x = 12 and y = 9
