Diego spent $3100 on a laptop, a VR headset, and a gaming mouse. The laptop cost $1900 more than the mouse and VR headset combined. The VR headset cost three times as much as the mouse. How much did the VR headset cost?
+313 Let's say the laptop costs 6x. the VR headset costs $y. The laptop cost $2. So { x + y + z = 3100 1
{ x - (y+z) = 1900 2
{ y = 32 3
3->2 x - 42 = 1900 4
3->1 x + 42 = 3100 5
4+5 2x = 5000 x = 2500
x - 42 = 1900 z=150
y = 32 y = 450
450 is the answer
