31.) you decide to market your own custom computer software. you must invest $3,255 for computer hardware, and spend $2.90 to buy and package each disk. if each program sells for $13.75, how many copies must you sell to break even?

a.) 301 copies

b.) 300 copies

c.) 195 copies

d.) 196 copies

B. 300 Copies

Step-by-step explanation:

So inplace of the copies you input the value x. Then, create an equation...

3,255= 13.75x -2.90x

3,255= 10.85x

Next you have to isolate x

3,255/10.85 = 300

so, 300=x

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
