P=r x 2 x pi
= 3 x 2 x 3.14
= 6 x 3.14 = 18.84
1 week = 7 days....so 1 week and 1/2 day = 7.5 days
2760 / 7.5 = 368 miles per day <==
S=Selling price 135
V=Variable cost 75
F=Fixed cost 3300
Let quantity be Q
The formula to break even is
135Q-75Q-3300=0
Solve for Q
60Q-3300=0
60Q=3300
Q=3300/60
Q=50
So the store must sell 50 bicycles to break even
Hope it helps!
