Answer:
Jack has to sell the old computers worth $8000
Step-by-step explanation:
Jack is paid for selling used computers = $15 per hour plus 5% commission
Let the revenue generated from selling the computers by him = $x
He will be paid for 40 hours = $(40×15) = $600
Commission earned by selling x computers = $0.05x
Total amount earned by him in 40 hours week = 600 + 0.05x
If this amount is $1000,
$1000 = $(600 + 0.05x)
0.05x = 1000 - 600
0.05x = 400
x = 
x = $8000
Therefore, Jack has to sell the old computers worth $8000.

Should be C. 1/19. because if there's 20 maebles in the bag and without replacing the marble then it actually would be 2/18
<span>1) 3x-2=x+10
</span><span>Now, lets solve this step-by-step.
</span><span>
3x - 2 = x + 10
-x -x
</span><span>
</span><span>3x - x = 2x 2x - 2 = 10
</span><span>
</span><span>2x - 2 = 10
</span>2x - 2+2 = 10+2 The inverse operation helps isolate the variable.
<span>
2x = 12
2x/2 = 12/2
x = 12/2
x = 6</span><span>
Answer: x = 6
2) x + 4 = 19 - 2x </span>
We can solve this much faster
x + 4 = 19 - 2x
+2x
x+2x = 3x
3x + 4 = 19
-4 -4
19-4 = 15
3x= 15
3x/3 = 15/3
x= 5
Answer: x = 5
3) <span>8x - 20 = x + 15
Much faster now!!
8x - 20 = x + 15
-x
8x-x = 7x
7x - 20 = 15
+20 +20
15+20 = 35
7x = 35
7x/7 = 35/7
x = 35/7
x = 5
Answer: x= 5</span>
