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!
Answer:
C
Step-by-step explanation:
Given x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 20 , y = 10 then
10 = 20k ( divide both sides by 20 )
= = k
y = x ← equation of variation → C
Let x be the number of texts (amount of texts) Carly does in a month.
Let y be the "total" amount Carly will have to pay in a month.
Then, as per the TURKEY plan, Carly's monthly total cost will be represented by the equation as shown:
As we can clearly see in the above equation even if Carly does not text a single message (when x=0), even then they will have to pay $20 for that month.
For the GOBBLE plan, the equation will be: .
In this plan as there is no fixed charge, Carly wont have to pay anything extra if they dont make a call.
The answer is A hope it helps
