A newly opened middle school’s enrollment is currently at 400 students. However, the school is implementing new programs and incentive systems to attract more students. They are projecting a 125% increase in enrollment for the upcoming school year. How many students does the school project to have for the upcoming school year?

I DON'T need the answer, I need to know how you solved it, don't just look up the answer and say that.

500

Step-by-step explanation:

400 x 1.25 = 500 or just 400x0.25 +400

900

Step-by-step explanation:

400x1.25=500

500+400=900

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
