A electronic company has developed a new hand held device the company predicts that the start up cost manufacture the new product will be 125,000 and the cost to make one device will be 7.15. Suppose the company wants to start making a profit after selling the number of devices of 50000. What should the new wholesale price be? Explain how you found your answer.

profit = revenue - expenses

expenses : 125,000 + 6.50x

revenue : 9x

so to make a profit, ur revenue (income) has to be higher then ur expenses

revenue > expenses

A. ) 9x > 125,000 + 6.50x

9x - 6.50x > 125,000

2.5x > 125,000

x > 125,000 / 2.5

x > 50,000so they would have to sell at least 50,001 devices to make a profit <==

B.) the cost of making 1 device is 10% more then the company predicted10% more then 6.506.50(1.10) = 7.15this is the new cost of making 1 device <==

9x > 125,000 + 7.15x this is the inequality with the 10% more added

9x - 7.15x > 125,000

1.85x > 125,000

x > 125,000 / 1.85

x > 67,567.5so to make a profit, they would have to sell at least 67,568 devices to make a profit <==

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
