cost $7.00. You can buy 7 oranges
for $12.50.
Is the relationship between the number of
oranges and their price proportional?
Explained step by step please

Answer 1

Answer:

True

Explanation:

Let's call

x: number of oranges

y: price

The relationship between x and y is proportional if they fulfill the following condition.

y / x = k

where,

k is a proportionality constant

Then,

6 / 4 = 15 / 10 = 1.5

Since x and y fulfill the condition, they have a relationship of proportionality.
