Answer:

a) Constant of proportionality = 0.25

b) The constant of proportionality provides the cost of one apple.

c) n = 12

Step-by-step explanation:

It is given that:

c = 0.25n

a) Here,

c = cost of apples

n = number of apples

As the proportion varies directly.

c ∝ n

c = kn

Comparing the equations

k = 0.25

b) The constant of proportionality provides the cost of one apple.

c) Putting c = $3

3 = 0.25n

Dividing both sides by 0.25

n = 12

Thus,

a) Constant of proportionality = 0.25

b) The constant of proportionality provides the cost of one apple.

c) n = 12
