PLEASE HELP QUICK 20 POINTS. Please as quick as possible I should have the answer in3 hours THANKS This year, You’ve decided to take your mother’s sedan car. When she filled the tank, it recorded the miles as 15,004. It took 71.98$ to fill up the vehicle’s empty gas tank. So what do you think is the size of the tank of your mother’s tank in gallons? Round your answer to the nearest whole number.(Remember the cost of every gallon is 3.99$)

18 gallons

Step-by-step explanation:

the tank capacity is :

$71.98 ÷ $3.98 = 18 gallons

i believe

step-by-step explanation:

from my conclusion c

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
