Question

A 5-lb bag of apples costs 4.50 and an 8-lb bag of the same type of apple costs 7.52. Greg found the unit price which is the contact of proportionality between cost and weight for each bag of apple.

Answer 1

Answer:

The unit price of 5-lb bag is less than the unit price of 8lb bag.

Step-by-step explanation:

Consider the provided information.

We need to calculate the unite price,

It is given that A 5-lb bag of apples costs 4.50

Calculate the unit price as shown:

$\frac{Cost}{weight} =\frac{4.50}{5}$

We need the cost of  1 l b .

$\frac{Cost}{weight} =\frac{4.50\div5 }{5\div 5}$

$\frac{Cost}{weight} =\frac{0.90}{1}$

So, the cost of 1lb of apple is $0.90.

8-lb bag of the same type of apple costs 7.52.

Calculate the unit price as shown:

$\frac{Cost}{weight} =\frac{7.52}{8}$

We need the cost of  1 l b .

$\frac{Cost}{weight} =\frac{7.52\div8 }{8\div 8}$

$\frac{Cost}{weight} =\frac{0.94}{1}$

So, the cost of 1lb of apple is $0.94.

Therefore, the unit price of 5-lb bag is less than the unit price of 8lb bag.
