$2\mathrm{.}30$ 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:

printf$("$Amount: $$\%0\mathrm{.}2$lf

$",$ dollars$)$;

Ex: If the input is:

$314$

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{.}252\mathrm{.}30$ 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:

printf$("$Amount: $$$0\mathrm{.}21\frac{f}{?}$

$,$ dollars$)$;

Ex: If the input is:

$3,1,4$

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.

$523848\mathrm{.}4012008$

I keep getting $1\mathrm{.}05$ instead of $1\mathrm{.}25.$ Not quite sure what I am doing wrong. please help!
