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 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

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
