3. An electronics company has developed a new hand-held device. The company predicts that the start-up cost to manufacture the new product will be $125,000, and the cost to make one
device will be $6.50.
a. 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.
b. The cost of one device is 10% more than the company predicted. What is the new cost of
making one device? How many devices must they now sell at the same price to make a profit?

c. Suppose the company wants to start making a profit after selling the same number of
devices you found in part a. What is the lowest the new price can be? Explain how you
found this price

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
