So this translates to:
5e + 5n = 25.95
2e + 6n = 22.38
One way to solve that is to multiply the top equation by 2, and the bottom equation by 5:
10e + 10n = 51.90
10e + 30n = 111.90
Then subtract the top from the bottom to get:
20n = 60
and divide by 20 to get
n = 3
So you know that note paper costs $3. Substituting that into the top equation you get:
5e + 5*3 = 25.95 or
5e + 15 = 25.95
Subtracting 15 from both sides you get:
5e = 10.95
Dividing by 5 you get:
e = $2.19
The statement that correctly describes a property of white light is that it b) contains different wavelengths of visible light.
When white light strikes any object that reflects any wavelength of visible light, that object appears to be the color that it reflects.
