A computer and printer cost total of $927 the cost of the computer is two times the cost of the planet find the cost of each ite
swat32

The cost of the printer is $309 and cost of the computer is $618.

Step-by-step explanation:

Let x denote the cost of computer

Let y denote the cost of printer

Total cost of printer and computer OR

x + y = $927

<u>To find the cost of x and y,</u>

Cost of computer = 2 x cost of the planet

x = 2y

x+y = 927

2y+y = 927

3y = 927

y = 309

x = 2y

x = 2(309)

x = 618

Therefore, the cost of the printer is $309 and cost of the computer is $618.
