Nike is planning to launch a new running shoe. The manufacturing of the shoe requires a fixed cost of $300,000. Additionally, it costs $15 to produce each pair of shoes. The new shoes will be sold at a price of $140 per pair. How many pairs of running shoes does Nike need to sell to break even? Define the variables:

Write the system of equations:

Solve:

but there’s no any figure there!

step-by-step explanation:

(sorry i'm not typing it again just read the other two explanation sections i just typed it'll be the same.)

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
