Final answer:
The amount lost is $0.55 or 0.55 as a decimal.
Step-by-step explanation:
To calculate the total amount lost, we need to add up the values of one quarter, two dimes, and two nickels. One quarter is equal to $0.25, two dimes are equal to $0.20 (since each dime is worth $0.10), and two nickels are equal to $0.10 (since each nickel is worth $0.05). Adding these values together, we get $0.25 + $0.20 + $0.10 = $0.55.
Therefore, the amount lost is $0.55, which is equivalent to 0.55 as a decimal.
