A car rental company charges an initial fee plus a constant fee per kilometer driven. The table compares the total distance driven on the trip (in kilometers) and the price of the rental (in dollars).

Distance (kilometers) Price (dollars)

105 183

140 204

175 225

What is the company's initial fee?

$120

Step-by-step explanation:

constant fee = (204-183) /(140-105)

= 21/35 = $0.6 per km

so, initial fee =

183 - (105 × 0.6)

= 183 - 63

= 120

just sum

10 + 10 = 20

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
