A. p = 0.42n
B. P = 2.52n
C. p = 6n
D. p = 15.12n

Answer 1

i think its A because the amount for one orange is .42

Answer 2

The correct answer is option A

Explanation:

Cost of the oranges is directly proportional to the number of oranges

Thus ,

p ∝ n -------------------------- Eq (A)

`p = kn\\`

cost of
`6 \\` oranges is equal to $
`2.52\\`

Cost of
`1\\` orange is equal to
`= (2.52)/(6) \\= 0.42\\`

Thus, Eq (A) can be re-written as

`p = 0.42 n\\`

Thus, the correct answer is option A
