Answer:
Fv = future value
Pv = present value
Fv = Pv (1+ it)
= $5,630( 1+0.04 (2))
= $6080.4
Fv = Pv + interest
$6080.4 = $5,630 +interest
interest = $6080.4 - $5,630 = $450.40
Step-by-step explanation:
3 + 5x = 20 + 7x
First subtract 20 to both sides
-17 + 5x = 7x
Next subtract 5x to both sides (we are trying to get x all in one side)
-17 = 2x
Divide 2 to isolate the x
-17/2 = x or -8.5 = x
I believe the answer would be 8 because jack will not move
