Step-by-step explanation:
100e^(.05t) = 150 . . . . . a better model of the situation
e^(.05t) = 150/100 . . . . divide by 100
0.05t = ln(1.5) . . . . . . . . take natural logs
t = ln(1.5)/0.05 ≈ 8.11 . . . . divide by the coefficient of t

Answer:

Step-by-step explanation:
Given equation:

Expand the left side:

Let all terms on the left side have the same denominator of 7:

Join the terms on the left side:


Let all the terms on the right side have the same denominator of 3:

Join the terms on the right side:


Cross multiply:

Expand:

Add 12x to both sides:

Add 252 to both sides:

Divide both sides by 40:
