Which inequality models this problem?
eduardo started a business selling sporting goods. he spent $7500 to obtain his merchandise, and it costs him $300 per week for general expenses. he earns $850 per week in sales.
what is the minimum number of weeks it will take for eduardo to make a profit?
300w> 7500+850w
850w> 7500+300w
850w< 7500+300w
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=

He earns $850 per week in sales.

i.e. Earning =

For profit , Earnings > Expenditure

i.e.

Subtract 300 from both sides .

Divide both sides by 550, we get

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

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
