Anna has decided to purchase a small car with a small gas tank. If x represents the number of miles driven, which linear function would best ESTIMATE the gas in Anna's tank as she drives? A) y = 20 - 0.05x B) y = 25 - 0.05x C) y = 12 + 0.05x D) y = 10 - 0.05x

Respuesta :

The correct answer to this is y = 10 - 0.05x which is D.

Answer:

10 - 0.05x

Step-by-step explanation:

Suppose

Amount of gas in gallons that car has initially=  A

Miles drove by Anna= x

total Gas consumed per mile = 0.05 gallon

Now the amount of gas left can be calculated as

Gas Left = Initial Amount - (gallons consumed per miles)(miles traveled)

Gas Left = A - 0.05x

Now placing the value of initial amount of gas (A) present in the car tank one can calculate the actual formula.

Suppose if the car had initially 10 gallons of gas in the tank, then our final formula is

Gas Left = 10 - 0.05x
