8 nickels
9 nickels
11 nickels

9 nickels

Step-by-step explanation:

9 nickels

Step-by-step explanation:

He doesn't have that many coins, and there are 4 choices, so let's use the guess method.

Try 7 nickels.

7 * $0.05 = $0.35

16 - 7 = 9

9 * $0.25 = $2.25

The quarters alone are worth more than $2.20, so this is not the answer. We need more nickels and fewer quarters.

Try 11 nickels.

11 * $0.05 = $0.55

16 - 11 = 5

5 * $0.25 = $1.25

$0.55 + $1.25 = $1.80

The coins are worth too little. We need fewer nickels and more quarters.

Try 9 nickels.

9 * $0.05 = $0.45

16 - 9 = 7

7 * $0.25 = $1.75

$0.45 + $1.75 = $2.20

The coins are worth the correct amount.

9 nickels
