40000*1/4=10000
10000=40000(0.85)^t solve for t
t=log(10,000÷40,000)÷log(0.85)
t=8.5 years
Less than one-fourth
Assume 9000
T=log(9,000÷40,000)÷log(0.85)
T=9 years
Answer: w = 9
Isolate the variable by dividing each side by factors that don't contain the variable. First, we rearrange the terms.
18 + 4w = 6w
4w + 18 = 6w
Now we subtract 18 from both sides.
When we simplify, we get that w = 9.
