Question

Reasoning A salesperson's commission rate is 4%. What is the commission from the sale of

$33,000 worth of furnaces? Use pencil and paper. Suppose sales would double. What would be
true about the commission? Explain without using any calculations

Answer 1

A salesperson earns 4% commission on furnace sales

The furnace sales have worth $33,000

We need to find the commission that the salesperson earns

∵ The salesperson earns 4% commission on furnaces sale

∵ The furnaces sale have worth $33,000

- Find the 4% of 33,000

∴ The salesperson earns 4% of 33,000

∵ 4% × 33,000 = \frac{4}{100}1004 × 33,000 = 1320

∴ The salesperson earns $1320

The commission that the salesperson earns on the sale is $1320

∵ The salesperson doubles his sales of furnaces

∴ The commission would be double

That because the commission is a constant percent from his sales of furnaces, so if the amount of his sales of furnaces doubles , then his commission also doubles, it is a direct proportion relationship

Commission = constant (4%) × amount of furnaces sale

The commission would be double when he doubles his sales of furnaces
