Car A costs $25.95 to rent and $0.35/km to drive. Car B costs $19.95 to rent and $0.55/km to drive. Let y represent the total cost to rent a car and m represent the number of kilometers a person drives. If you are solving the equation, how many km would you have to drive for the total cost to be the same? 0.35m + 25.95= 0.55m + 19.95

1) 60 kilometers for them to be the same

2) 6 kilometers for them to be the same

3) 12 kilometers for them to be the same

4) 30 kilometers for them to be the same

i think it's 1

Step-by-step explanation:

I think it is 4

Step-by-step explanation:

dont know

step-by-step explanation:

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
