I need help with all of it please:)

Extracted text: The total cost of a ride, C, in British pounds (GBP), on BlackCabs can be modelled by the function C = 1.75x + 3.00, where r is the distance travelled in kilometres. (a) Calculate the total cost of an 8 kilometre ride in a BlackCab. (b) On the grid below, sketch the graph of the function C = 1.75x + 3.00, for x > 0. C 20 15 10 4 6 8. (c) Calculate the distance travelled, x, in kilometres, when the total cost of a ride reach 45 GBP. The starting fare of MiniCabs is 2.00 GBP higher than of BlackCabs, however the ride fare is lower at 1.40 GBP per kilometre travelled. (d) Find the least number of whole kilometres required to travel for the total cost to be less on a MiniCab ride in comparison to a BlackCab ride.
