HELP ASAP The measure of angle NCB is 113°.

What is the measure of angle BCG?

Enter your answer in the box.

Step-by-step explanation:

For this problem, the cost for renting a car is based on a flat rate of $/mile

You need to know that the rate = cost/distance  

(a)  That expression can be rearranged by multiplying both sides by distance:  rate • distance = cost

The cost (y) =  the rate ($/mile) times the distance driven (x):   y ($) = rate ($/mi) • x (mi) with the units in ( )

You are given information to calculate the rate for two drivers:

For Mike, x = 30 miles and the cost = $22.50, and rate = cost/distance

                                                                            rate = $22.50 / 30 miles  =  $0.75/mile

For Ben, x = 50 miles and the cost is $31.50;  rate = $31.50 / 50 miles = $0.63

Ben pays a lower rate than Mike.

(b) for Mike's travel:

      rearrange the equation cost =  rate • distance to solve for distance by dividing both sides by rate:

      cost / rate = distance • rate / rate  

      rewriting, distance = cost / rate = $21.00/($0.75/mile) = 28 miles

(c) You may have missed part of this question.  Parts (c) and (d) questions make no sense since there is no information given for a "cab".
