Please help me solve this, mathematicians in the house

Does this mean that no one from this forum can solve this question on bearing and distance?

Let the starting point be B and the stopping be C as shown in the diagram below.
therefore, the angle at A will be (197-90)degree = 107degree
the angle at B is 45degree, since it is directly south west of C.
therefore the angle at C will be A+B+C=180 degree(sum angle of a triangle)
107+45+C=180
therefore, C=180-107-45=28degree
therefore, using sine rule gives;
sinA/a =sinC/c
sin107/a=sin28/4
0.9563/a=0.4695/4
0.9563/a=0.11736
therefore, a =0.9563/0.11736=8.148=8.1km(approx.)

This is the question


To start a new transport company, a business man needs at least 5buses and 10 minibuses he his not able to run more than 30 vehicle altogether. A bus takes up 3unit of parking space,a minibus takes up 1 unit of parking space and their are only 54 unit available

A. Draw a graph showing a region representing possible way of success

B. If the daily running cost of bus and a mini bus are #4500 and #2400 respectively

i. What is the objective function for the total running cost per day
ii. Find the maximum daily cost and the corresponding numbers of buses and mini buses

iii. Find the minimum daily cost and the corresponding number of buses and mini buses
