$2\mathrm{.}31$ LAB: Convert to dollars

Given three input values representing counts of nickels, dimes, and quarters, output the total amount as dollars and cents.

Output each floating$-$point value with two digits after the decimal point using the following statement:

Ex: If the input is:

where $3$ is the number of nickels $($at $$0\mathrm{.}05$ each$),1$ is the number of dimes $($at $$0\mathrm{.}10$ each$),$ and $4$ is the number of quarters $($at $$0\mathrm{.}25$ each$),$ the output is:

Amount: $$1\mathrm{.}25$

For simplicity, assume input is non$-$negative.
