Answer:

  • Mark: s = 200 +20j
  • Ryan: s = 350 +15j
  • 30 jobs

Step-by-step explanation:

The amount in savings (s) will be the initial amount plus the product of the pay per job and the number of jobs (j).

<u>Mark</u>

He initially has $200, and is paid $20 per job. His savings will be ...

  s = 200 +20j

<u>Ryan</u>

He initially has $350, and is paid $15 per job. His savings will be ...

  s = 350 +15j

<u>Same Savings</u>

The savings will be the same when the difference between the amounts is zero:

  s - s = 0

  (200 +20j) -(350 +15j) = 0 . . . . . substitute the expressions for s

  -150 +5j = 0 . . . . . collect terms

  -30 +j = 0 . . . . . . . divide by 5

  j = 30 . . . . . . add 30

The brothers will have the same amount in savings after they each work 30 jobs.

Think how many triangles could you fit within the top of the area (vertex). So split the shape in half and you could atleast fit 4 triangles in it. So I would say 4+ maybe?
