Final Examination Number:…………….. Name/Surname:…………….. Signature:………………. 1) The tax rate is 10% of the first $1000 and 20% of all additional income. Design an algorithm for printing the gross pay, the tax with held, and net pay of an employee, given the numbers of hours worked and hourly wage rate. The desired algorithm is as fallows: 1.1. Read hours worked and wage rate 1.2. Do computations:

1.2.1. Compute gross pay: gross pay = hours worked x wage rate 1.2.2. Compute tax: if gross pay is less than 10000 then tax = 0.1 x gross pay otherwise tax = 100 + 0.2 x (gross pay – 1000) 1.2.3. compute net pay: net pay = gross pay –tax

1.3. print gross pay, tax and net pay 1.4. Stop. 2) Write C expressions for the following mathematical expression.
