kobusy [5.1K]

Answer:

a) UNIT PRICE of  potatoes is $0.56

b) UNIT PRICE of  broccoli  is $3.1

c) UNIT PRICE of  broccoli  is $0.98

Step-by-step explanation:

UNIT PRICE is defined as the price of 1 unit.

\textrm{Unit Price} = \frac{\textrm{Total cost on n products}}{\textrm{n}}

Now, here in the given question:

1.  Cost of  4.5 pounds of potatoes is  $2.52

So, the unit price of potatoes  = \frac{\textrm{2.52}}{\textrm{4.5}} = 0.56

⇒ 1 pound of potatoes cost $0.56

Hence,UNIT PRICE of  potatoes is $0.56

2  Cost of  2.5 pounds of broccoli is $7.75.

So, the cost of 1 pound of broccoli  = \frac{\textrm{7.75}}{\textrm{2.5}} = 3.1

⇒  1 pound of  broccoli cost $3.1

Hence,UNIT PRICE of  broccoli  is $3.1

3.  Cost of 2.5 pounds of pears is $2.45.

So, the cost of 1 pound of pears  = \frac{\textrm{2.45}}{\textrm{2.5}} = 0.98

⇒ 1 pound of pears cost $0.98

Hence,UNIT PRICE of  broccoli  is $0.98
