Not sure bud, but I think it's transactions.
The formula is
A=p (1+rt)
A future value 1650
P present value 1200
R interest rate 0.08
T time?
1650=1200 (1+0.08t)
Solve for t
Divide both sides by 1200
1650/1200=1+0.08t
Subtract 1 for both sides
(1650/1200)-1=0.08t
Divide both sides by 0.08
T=((1,650÷1,200)−1)÷0.08
T=4.69 years round your answer to get 5 years
Another way using the formula of simple interest
I=prt
I interest earned which can be found by subtracting the present value from the future value (A-p)=1650-1200=450.
P principle 1200
R interest rate 0.08
T time?
Solve the formula for t
T=I/pr
T=450÷(1200×0.08)
T=4.69 years round your answer to get 5 years
Hope it helps!

Explanation:
Hi
First of all, we need to know how much will cost the land in five years so we have,
