A bicycle store costs ​$3300 per month to operate. The store pays an average of ​$75 per bike. The average selling price of each
Klio2033 [76]
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!

Find the value of y in the given triangle
Andre45 [30]

Given:

In the given triangle,

With respect to y, Perpendicular = 10 cm and Base = 8 cm

To find the value of y.

Formula

By Trigonometric Ratio we get,

tan\theta = \frac{Perpendicular}{Base}

Now,

Putting the values of perpendicular and base we get,

tan\theta = \frac{10}{8}

or, \theta = tan^{-1} (\frac{10}{8})

or, \theta = 51.34 ^\circ

Rounding off to the nearest tenth, we have;

\theta = 51.3 ^\circ

Hence,

The value of y is 51.3°.
