for the first question on the final review the output is wrong for the commission of sales price > 20000.

Wed, 13 Feb 2019 15:45:41 +0000

In the first question shes has :

Enter sales price (-1 to stop): 8000
Commission is $160.00

Enter sales price (-1 to stop): 15000
Commission is $275.00

Enter sales price (-1 to stop): 30000
Commission is $450.00

Enter sales price (-1 to stop): -1

Total sales commission = $885.00

but the arithmetic is wrong. She has us do $350 + 1% for a sale over 20000.
but if you do 30000 * .01 that is 300 + 350 = 650 not 450.

my output is:
Enter sales price (-1 to stop): 8000
Commission is $160.00

Enter sales price (-1 to stop): 15000
Commission is $425.00

Enter sales price (-1 to stop): 30000
Commission is $650.00

Enter sales price (-1 to stop): -1

Total sales Commission = $1235.00

this also doesnt work for the computation of 15000.

am i right or wrong?
