Answer:

900

Step-by-step explanation:

set both options equal to each other so we know the intersection.

30000 + 20t = 21000 + 30t

now solve for t.

10t = 30000-21000

t = 90000/10

t = 900

The second option is your answer.

2(1) - 3 = 2 - 3 = - 1

2(2) - 3 = 4 - 3 = 1

2(3) - 3 = 6 - 3 = 3

2(4) - 3 = 8 - 3 = 5

- 1 + 1 + 3 + 5 = 8

$7 - 4(2w + 1) = 9w - 49 + w \\ 7 - 8w - 4 = 10w - 49 \\ 10w + 8w = 7 - 4 + 49 \\ 18w = 52 \\ w = \frac{52}{18} \\ w= 2.88$

I hope I helped you^_^
