Hi,
Answer: 0.24 per liter
<u>My work:</u> This problem is easily achievable all you have to do is take your caculator and take price Melvin would pay with his loyalty card 1.679 and subtract it with 1.439. (1.679 - 1.439) When you do this you easily achieve your answer; Melvin pays 0.24 less per liter using his loyalty card.
I Hope it helped!

Y=125-20x ; the value of the cell phone after three years is $65.
Answer: 1.3 seconds
Step-by-step explanation:
Given: Distance of the moon to the Earth = 384,400 km = 384400 x 1000 meters = 384400000 meters. [1 km = 1000 m]
Speed of light =
m/s = 299800000 m/s
Formula: ![\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}](https://tex.z-dn.net/?f=%5Ctext%7BTime%7D%3D%5Cdfrac%7B%5Ctext%7BDistance%7D%7D%7B%5Ctext%7BSpeed%7D%7D)
Let <em>t</em> be the time taken by the light to travel from the moon to the Earth.
![t=\dfrac{384400000}{299800000}\approx1.3\text{ seconds}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B384400000%7D%7B299800000%7D%5Capprox1.3%5Ctext%7B%20seconds%7D)
Hence, it will take approximately 1.3 seconds for the light to travel from the moon to the Earth.
