Y equals 20 log base five of (50,000+2)+5

The linear function that expresses gallons sold as a function of price is .

The number of gallons sold at a price of $1.22 per gallon is 7206.8

Step-by-step explanation:

Consider the provided information.

A gas station sells 4820 gallons of regular unleaded gasoline in a day when they charge $1.35 per gallon,

They sell 3902 gallons on a day that they charge $1.40 per gallon.

Let x represents the price per gallon and y represents the number of gallons sold.

Thus the ordered pairs are (1.35,4820) and (1.40,3902)

Now find the slope of line using the formula:

Now find the slope intercept as shown:

Hence, the linear function that expresses gallons sold as a function of price is .

The number of gallons sold at a price of $1.22 per gallon.

Substitute x=1.22 in above equation.

Hence, the number of gallons sold at a price of $1.22 per gallon is 7206.8
