Answer 1

Answer:

4. 215

5. 20.04

Step-by-step explanation:

4. in this question the cost of one dozen is given and it is asking the cost of 7 dozens so just multiply the cost of one dozen with the no. of dozens

5. and in this question the cost of 9 colour pencils are given it means in total it costs 180.36 so for the cost of one colour pencil just divide the total sum or amount of money by the units of pencils which here is 9.
