Show work please. Just number 8..thank you..

Step-by-step explanation:

it’s a geometric sequence problem:

After 1 year : V1 = 1 000×1.06 = 1 060

After 2 year : V2 =  1 060×1.06 = 1 123.6

After 3 year : V3 = 1 123.6×1.06 = 1 191.016

.

.

.

After k year : Vk = 1000×(1.06)^k

We have to solve for k : Vk = 2000

Vk = 2000 ⇔ 1000×(1.06)^k = 2000 ⇔ (1.06)^k = 2 then k=12

verification : 1 000×(1.06)^(12) = 2 012.19647183555 ($)

step-by-step explanation:

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
