A bicycle store cost $3200 per month to operate. The store pays an average of $40 per bike. The average selling price of each bicycle is $120. How many bicycles must the stores sell each month to break even

40

Step-by-step explanation:

If the store is making selling bikes for 120 and the average they pay is 40 a bike then they're making an 80 dollar profit, and the profit is what you need to solve this equation. 3200/80 gets you 40, so you would need to sell an average of 40 bikes in order to break even

b.-4 units

all you   do is count how many times you move

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
