Answer: x
=
−
4
,
y
=
−
11
Step-by-step explanation:
The answer is 720 mph, since we make time the x and distance y. We use the slope formula (y2 - y1)/(x2 - x1)
(179-23)/(17-4)
156 miles/13 mins
12 miles per min
Since the answer is in hours instead of minutes, we multiply 12 by 60 to get 720 mph
(a) The profit when the company sold 1000 pens is -1000.
(b) The number of pens that are required to sell in the break-even is 1167.
(a)
The profit when the company sold 1000 pens is
P = R - C
= 9x - (3x + 7000)
= (9 × 1000) - (3 × 1000 + 7000)
= 9000 - (3000 + 7000)
= 9000 - 10000
= -1000
(b)
The number of pens that are required to sell in the break-even is
R = C
9x = 3x + 7000
9x - 3x = 7000
6x = 7000
x = 1167
Therefore we can conclude that:
(a) The profit when the company sold 1000 pens is -1000.
(b) The number of pens that are required to sell in the break-even is 1167.
