Q2. Betty has a part-time job selling bullding products which pays per week and commission
onsales made
a. How much would Detty earn in a week if she made no sales? (1 mark)
b. If Betty old worth of building products in a week, how much would she earn?
[ 2 mark ।
c. If Betty old worth of materials in one week and worth in the next, find her
average Neekly income for the two weeks ( 4 marks)

If Betty made no sales, she would earn her fixed weekly salary of $100. Commission only applies when sales are made, so in a week with no sales, her total earnings would simply be that salary. It’s a nice little security blanket for part-time workers like her!

Now, about that commission! If Betty sold $18,000 worth of building products, her commission would be $18,000 multiplied by 2%, which is $360. Adding her base salary of $100, her total earnings for that week would be $460. That’s quite a nice paycheck for her hard work!

For her average weekly income over two weeks, we first need to calculate her earnings for each week. In the first week, with $24,000 in sales, her commission would be $480 (2% of $24,000) plus her $100 salary, leading to $580. In the second week, selling $5,000 would give her a commission of $100, so she would earn $200 that week in total. To find the average, we sum both weeks’ earnings ($580 + $200 = $780) and divide by 2, resulting in an average weekly income of $390. It’s a clear reminder that hard work pays off!
