Write a python program to calculate the cost for replacing carpet for a single room. Carpet is priced by square foot. Total cost includes carpet, labor and sales tax. Dollar values are output with two decimals. For example, print$($f$\text{'}$Cost: $$\{$cost:$\mathrm{.}2$f$\}\text{'}).$Read from input the carpet price per square foot $($float$),$ room width $($int$)$ and room length $($int$).$ Calculate the room area in square feet. Calculate the carpet price based on square feet with an additional $20\%$ for waste. Output square feet and carpet cost. Submit for grading to confirm $1$ test passes.Calculate the labor cost for installation $($$$0\mathrm{.}75$ per actual square foot$).$ Output labor cost. Submit for grading to confirm $2$ tests pass.Calculate sales tax $(7\%)$ on carpet and labor cost. Total cost includes carpet, labor and sales tax. Output sales tax and total cost. Submit for grading to confirm $3$ tests pass. Repeat steps $1-3$ including additional input for a second order $($one order per line$).$ Maintain total sales for both orders. Output information for each order with a heading and then total sales for both orders. Submit for grading to confirm $4$ tests pass.Repeat steps $1-3$ including additional input for a third order $($one order per line$).$ Maintain total sales for all orders. Output information for each order with a heading and then total sales for all orders. Submit for grading to confirm all tests pass.
