A salesman gets a commission of 2.4% on sales up to Shillings 100,000. He gets an additional commission of 1.5% on sales above this. Calculate the commission he gets on sales wroth shillings 280,000.

100000(.024) + 0.015(280000 - 100000)
2400 + 2700
5100

the arithmetic looks good.

I would insist on an equal sign in front of each new line

commission
= 100000(.024) + 0.015(280000 - 100000)
= 2400 + 2700
= 5100

The answer is legit...nice work

To calculate the commission the salesman gets on sales worth Shillings 280,000, you can use the following formula:

Commission = (Commission rate on sales up to Shillings 100,000) + (Commission rate on sales above Shillings 100,000) * (Sales above Shillings 100,000)

Let's break it down step by step:

1. Calculate the commission on sales up to Shillings 100,000:
Commission on sales up to Shillings 100,000 = 100,000 * 0.024 = Shillings 2,400

2. Calculate the commission on sales above Shillings 100,000:
Sales above Shillings 100,000 = 280,000 - 100,000 = Shillings 180,000
Commission rate on sales above Shillings 100,000 = 0.015
Commission on sales above Shillings 100,000 = 180,000 * 0.015 = Shillings 2,700

3. Add the commissions from step 1 and step 2 to get the total commission:
Total Commission = 2,400 + 2,700 = Shillings 5,100

Therefore, the salesman gets a commission of Shillings 5,100 on sales worth Shillings 280,000.
