Answer
Roy has $0.92 or 92 cents on him.
Step-by-step explanation
We need to lnow the worth of each of those coins before knowing the total worth of money that Roy has.
1 nickel = 5 cents = $0.05
1 quarter = 25 cents = $0.25
1 dime = 10 cents = $0.10
1 penny = 1 cent = $0.01
Roy has 3 nickels, 2 quarters, 2 dimes, and 7 pennies.
3 nickels = 3 × $0.05 = $0.15
2 quarters = 2 × $0.25 = $0.50
2 dimes = 2 × $0.10 = $0.20
7 pennies = 7 × $0.01 = $0.07
All of Roy's money is then
(3 nickels) + (2 quarters) + (2 dimes) + (7 pennies)
$0.15 + $0.50 + $0.20 + $0.07
= $0.92
Hope this Helps!!!
