WILL GIVE BRAINLIEST A boy had 20 cents. He bought x pencils for 3 cents each. If y equals the number of pennies left, write an equation showing the dependence of y on x. What is the domain of the function?

Step-by-step explanation:

If the boy initially had 20 cents, then the total number of cents he will have left after purchasing pencils is equal to the total cost of the pencils subtracted from 20. The total cost of pencils, in cents, is equal to , since each pencil is 3 cents.

Therefore, the total amount, in cents, that the boy has left, , is equal to :

The domain of this function is or all real numbers .

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
