#### Answer

Get values for balance, purchases, payment Set the value of unpaid to balance + purchases - payment If unpaid < 100 then $\ \ \ \ \ \$ Set the value of interest to unpaid $\times$ 0.08 Else $\ \ \ \ \ \$ If unpaid $\leq$ 500 then $\ \ \ \ \ \$ $\ \ \ \ \ \$ Set the value of interest to unpaid $\times$ 0.12 $\ \ \ \ \ \$ Else $\ \ \ \ \ \$ Set the value of interest to unpaid $\times$ 0.16 Set the value of newbalance to unpaid + interest Print the value of newbalance Stop
