Ahmad buys apples from the local orchard. The table below shows the relationship between the cost (in dollars) and the weight (in kilograms) of the apples purchased.
Weight
(kilograms) 0 1 2 3
Cost
(dollars) 0 3 6 9
(a)For the information in the table, write an equation to represent the relationship between C and W.
(b)Choose the correct statement to represent this relationship.
Apples cost 1 dollar per 3 kilograms.
Apples cost 9 dollars per kilogram.
Apples cost 1 dollar per kilogram.
Apples cost 3 dollars per kilogram.
(a) The equation that represents the relationship between the cost (C) and weight (W) of the apples purchased is C = 3W.
(b) The correct statement to represent this relationship is "Apples cost 3 dollars per kilogram."
(a) To write an equation to represent the relationship between C (cost) and W (weight), we need to find the pattern in the data.
From the table, we can see that the cost increases by 3 dollars for each additional kilogram of apples.
So, we can write the equation as:
C = 3W
(b) The correct statement to represent this relationship is:
Apples cost 3 dollars per kilogram.
(a) To write an equation representing the relationship between C (cost in dollars) and W (weight in kilograms), we need to find the pattern or relationship between the two variables. Looking at the given table, we can observe that the cost increases by 3 dollars for every 1 kilogram increase in weight.
So, for every 1 kilogram increase, the cost increases by 3 dollars. This suggests a linear relationship between the cost and weight.
Therefore, the equation for the relationship between C and W can be written as:
C = 3W
(b) The correct statement to represent this relationship is: "Apples cost 3 dollars per kilogram."
