Tim uses his lorry to deliver turf
you can use this graph to find the delivery costs for different distances.
For each delivery there is a fixed charge plus a charge for distance
A) how much is the fixed charge?
Tim makes two delvers of turf. The distance of one delivery is 20 miles more than the distance of the other delivery.
B) What is the difference between the two delivery costs?

A) 12 pounds

B) 28 pounds

Step-by-step explanation:

Step 1 :

It is given that there is a fixed charge for every delivery and variable charge based on the distance.

The graph is plotted between distance (x-axis) and delivery cost (y-axis).

Step 2 :

A)  The value of y corresponding to x=0 represents the total charge for a distance of zero miles. This value would be the fixed charge. By observing the graph we can conclude that y=12 when x=0. Hence the fixed charge is 12 pounds.

Step 3 :

B) By observing the graph we can conclude that the total cost for a distance of twenty miles is 40 pounds.

This includes fixed charge and variable cost based on the distance.

The fixed cost is 12 ponds.

Hence variable cost is 40 - 12 = 28 pounds. The delivery cost per mile is 28/20=1.4 pounds.

It is given that the distance between the distance for the 2 deliveries is 20 miles. The fixed cost is the same for both deliveries. The difference in variable cost would be 1.4*20=28 pounds.

answer: 193

explanation:

200-7 = 193
