Answer:
It is c = kt.
Step-by-step explanation:
This is direct variation . As the time increases the number of cranes increases.
The equation is c = kt where k is the constant of variation. In this case it will be a positive value because c is increasing with time.
If they make 20 cranes in 10 minutes then we can find the value of k by plugging in these values;
20 = k * 10
g = 20/10
k = 2.
So they make 2 cranes per minute.

Answer:
The cost of the gas is £67.81 p
Step-by-step explanation:
Here we have
Initial gas reading = 8247
Final gas reading = 8631
Therefore the total consumed gas is given by
Final gas reading - Initial gas reading → 8631 - 8247 = 384
Since the cost of gas is 11p per unit we have, the total cost of the gas consumed is given by
Cost of consumed gas = Units of gas consumed × Unit cost of gas
= 384 × 11p = 4224 p
100 p ≡ £ 1
Therefore 4224 p = £42.24 p
The total cost of the gs is obtained by adding the fixed charge to the cost of gas consmed as follows
£25.57 + £42.24 = £67.81 p
The cost of the gas = £67.81 p
