0.45_0.9_1.8_2.25_4.5_6.75__9___45

Explanation:

Given the data:

Number of pepper: 1 2 4 5 10 15 20 100

Cost :

Cost of 5 pepper = 2.25

Using variation :

Cost = number of pepper * k

K = CONSTANT of proportionality

k = cost / number of pepper

k = 2.25 / 5

k = 0.45

Hence,

Cost of pepper = k * number of pepper

Number of pepper:
