# Calculation Section

After reading the food cost, the program can do the calculations. It is convenient to do them all at once and then to print out the results.

    ## rest.asm
    ##
    ## Total restaurant bill calculator
    ##
    ## Register Use:
    ##
    ## $s0 tip+tax
    ## $s1 tip rate
    ## $s2 tax rate
    ## $s3 meal cost
    ## $a0 tax+tip dollars

            .globl  main

            # Get meal cost
    main:       $v0,4       # print a prompt (code 4 put in $v0)
                $a0,prompt  # address of prompt put in $a0
            syscall

                $v0,5       # input an integer  (code 5 put in $v0)
            syscall             # 32-bit result returned in $v0
              $s3,$v0     # save it in $s3

            # Calculations
            lw      $s1,_____        # get tip rate

            lw      $s2,_____        # get tax rate

            addu    $s3,$s1,$s2      # total rate

            _____   $s4,$s0,$s3      # 100*(tax + tip)

            _____    $s4,$s4,100     # tax + tip

            _____  $s5,$s0,$s4       # total bill

           . . . . .

            .data
    tip:    .word   15          # tip rate in percent
    tax:    .word    8          # tax rate in percent

    prompt: .asciiz "Enter food cost: "
    head1 : .asciiz "   Tax plus tip: "
    head2 : .asciiz "     Total cost: "
