Consider the following simple program and note how repetitive it is to prompt for the inputs.

$```$

def main$()$ :

price$1=$ float$($input$("$First item: $"))$

print$()$

price$2=$ float$($input$("$Next item: $"))$

print$()$

rate $=$ float$($input$("$Tax rate in percent: $"))$

total $=$ price$1+$ price$2$

tax $=$ total $*$ rate $/100$

print$("$Amount due:", total $+$ tax$)$

$```$

Rearrange these lines of code into an alternate solution with a reusable helper function. Put the helper function after main and be sure to call the main function after the helper function definition. Empty print statements are included for output formatting.
