Answer: x = 14
Step-by-step explanation:
-x+14 = 0
Subtract 14 from both sides of the equation :
-x = -14
Multiply both sides of the equation by (-1) : x = 14
0.5=0.85^x taking the natural log of both sides...
ln0.5=x ln0.85
x=ln0.5/(ln0.85)
x≈4.265
Then:
f=20000(0.85)^(4.265)
f=$10000.00 to nearest dollar
