Question

A 5 pound Bag of apples cost 4.50 and a 8 pound bag of the same type of apples cost $7.52 Greg found that the unit price which is the cost of proportionality between cost and weight for each bag of apples what is the difference in the unit prices a. 0.04 per pound b. 0.12 per pound c. 0.16 per pound d. 0.21 per pound

Answer 1

Answer:

The difference in the unit prices is $0.04 per pound.

The answer is a. 0.04 per pound.

Step-by-step explanation:

Given:

A 5 pound Bag of apples cost 4.50 and a 8 pound bag of the same type of apples cost $7.52.

Now, to find the difference in the unit prices.

So, we get the unit price first for both quantities of apples 5 pound bag and 8 pound bag by using unitary method:

If, 5 pound bag of apples cost = $4.50.

Then, 1 pound bag of apples cost = $\frac{4.50}{5} =\ 0.90.$

Thus, the unit price of 5 pound bag of apples is 0.90 per pound.

Now, to get the unit price of 8 pound bag of apples:

If, 8 pound bag of apples cost = $7.52.

Then, 1 pound bag of apples cost = $\frac{7.52}{8} =\ 0.94.$

Hence, the unit price of 8 pound bag of apples is 0.94 per pound.

Now, to get the difference in the unit prices by subtracting the unit price of 5 pound bag of apples from the unit price of 8 pound bag of apples:

$\ 0.94-\ 0.90\\\\=\ 0.04.$

Thus, the difference in the unit prices = $0.04.

Therefore, the difference in the unit prices is $0.04 per pound.

The answer is a. 0.04 per pound.
