Question

Which inequality models this problem?

Answer 1

$850w \geqslant 7500 + 300w$

Answer 2

Answer: $850w>7500+300w$

The minimum number of weeks it will take for Eduardo to make a profit =14

Step-by-step explanation:

Let w represents the number of weeks.

Given : Eduardo started a business selling sporting goods.

He spent $7500 to obtain his merchandise, and it costs him $300 per week for general expenses.

i.e. Expenditure for w weeks= $7500+300w$

He earns $850 per week in sales.

i.e. Earning = $850w$

For profit , Earnings > Expenditure

i.e. $850w>7500+300w$

Subtract 300 from both sides .

$550w>7500$

Divide both sides by 550, we get

$w>13.6363636364\approx14$

Hence, the minimum number of weeks it will take for Eduardo to make a profit=14
