please answer this question A bicycle store costs $2400 per month to operate. The store pays an average of $60 per bicycle that is sold in the shop. This is called a company’s overhead. The average selling price of each bicycle is $120. How many bicycles must the store sell each month to break even?

40  

Step-by-step explanation:

                  Let b = the number of bicycles sold

         Then 120b = monthly income

And 2400 + 60b = monthly expenses

At the break-even point,

120b = 2400 + 60b

60b = 2400

     b = 40

The store must sell 40 bicycles per month to break even.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
