An electronics company has developed a new handheld device. The company predicts that the startup cost to manufacture the new product will be $225,000, and the cost to make one device will be $7.50. If the company plans on selling the devices at a price of $9, write and solve an inequality to determine how many must be sold for the company to make a profit. Show your work.

Best ResponseYou've already chosen the best response.1yes, so profit = 22500 now if we we want to make any money, profit, we need to sell devices, what would the eqwuation look like if I wanted to know how much money I make for each device I sell?

Best ResponseYou've already chosen the best response.1it would look like this: how much money is made when each device is sold=9*x where x is the number of devices sold

Best ResponseYou've already chosen the best response.1so now our equation would look like this: profit = 9*x 22500 can you do what I did with the 9x but with how much it costs to make each device?

Best ResponseYou've already chosen the best response.1very good, but I was a bit confusing when I asked you to do it ^_^ so now if we combine all the parts, the 22500 and 9*x and 7.50*x we get profit = 9x7.5x2500

Best ResponseYou've already chosen the best response.1profit = 9x7.5x22500 now we need to set the equation equal to x so we move the 22500 to the other side: 22500 = 9x7.5x now we factor out the x on the right side 22500 = x(97.5) simpilfy 22500 = x(1.5) divide both sides by 1.5 22500/1.5 = x now change the = sign to an inequality 22500/1.5 < x so in order for a company to make any profit, x must be greater than 22500/1.5 so, I sorta rushed it all at the end, but I have to go ^_^
