Kyle has a total of 16 coins in his pocket. all the coins are nickels or quarters, and they have a total value of $2.20. how many nickels does kyle have? 7 nickels 8 nickels 9 nickels 11 nickels

9 nickles

Step-by-step explanation:

A nickel is 5 cents or $0.05 and quarters are 25 cents or $0.25.

Let there be x nickles and y quarters.

The system of linear equation that would best represent the given scenario is:

x + y = 16  or y=16-x

0.05x + 0.25y = 2.20   or 5x+25y=220  or  x+5y=44

⇒ x+5(16-x)=44

⇒ x+80-5x=44

⇒ 4x=36

⇒ x=9

Thus, there are 9 nickels in his pocket.
