For an upcoming business trip, you are requesting a voucher for traveling expenses from your employer. Each expense is itemized separately. You will be traveling 175 miles to your destination and returning over the same route. The company car gets 35 miles per gallon using gasoline that costs $2.45 per gallon. Which is the appropriate calculation to perform SECOND when determining the dollar amount to request for gasoline?

what is the question?

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
