A salesman gets a commission of 51⁄2% of the value of items he sells. The salesman sells 12 textbooks at GH₵ 25.00 per book, 3 scientific calculators at GH₵ 50.00 per calculator and
8 packets of bic pens at GH₵ 50.00 per packet. Calculate the salesman's commission.
Show Solution
Total Amount Sold = 12 x GH₵ 25.00 + 3 x GH₵ 50.00 + 8 x GH₵ 50.00
Total Amount Sold = GH₵ 300.00 + GH₵ 150.00 + GH₵ 400.00
Total Amount Sold = GH₵ 850.00
Commission = Commission Percent/100 x Total Amount Sold
Change the mixed fraction to improper fraction
Percentage means over 100
NOTE: Every number is divisible by 1, hence 100 = 100/1
Apply the division of fraction rule
Now multiply by the total amount sold and simplify
