Answer:
The company has to produce more than 92 guitars and sell them for making a profit.
Step-by-step explanation:
These are the cost and revenue functions, where x represents the number of guitars to be manufactured and sold: R(x) = 120x, and C(x) = 100x + 1840.
Therefore, the condition for no loss-no gain for manufacturing x number of guitars is
R(x) = C(x)
⇒ 120x = 100x + 1840
⇒ 20x = 1840
⇒ x = 92
Therefore, the company has to produce more than 92 guitars and sell them for making a profit. (Answer)

Step-by-step explanation:
Jenny traveled 70 km/h over 2 hours and 63 km/h over 5 hours. Her travel time was a total of 7 hours.
We need to find out how far she traveled during this 7-hour period.
70 km/h * 2 h = 140 km
63 km/h * 5 h = 315 km
Then, we can add 140 km and 315 km to get a total distance traveled of <em>455 km/h.</em>
We were asked to find the average <em>speed.</em> We can find it now, since we have total distance traveled (455 km) and total time taken (7 hours).
Then,
455km / 7h = 65 km/h.
The numbers start from the top
