Answer:
2.3%
Step-by-step explanation:
For continous compound interest

Where A is final value, P is initial investment, i is interest rate in decimal and t is period.
The time will be 30-18=12 years
Substituting $14000 for A, $7000 for P and 12 years for t

Introducing natural logarithms on both sides then 12i=ln 2
Making i the subject of formula then
i=ln 2 ÷12=0.05776226504666
The percentage rounded off will be 5.7% p.a
The formula for point-slope form is y-a=m(x-c), where y and x are variables, a is simply one point in y, m is the slope, and c is simply one point in x. The first thing we can find is m, or the slope. This is found by dividing the change in y over the change in x. The equation for this is (I’ll plug the points in the equation)

Therefore, our answer is the bottom one as our slope is 1/4.
