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

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

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
