Step-by-step explanation:
Do 115000/100x6.5 You get 7.475k
Answer:
Step-by-step explanation:
It would be 72. You get that by doing 12 X 12 which is 144. Than divide it by 2 to get 72.
To get the smallest amount one can invest in 3 years at a rate of 5% to obtain £8000 we use the compound formula given by:
A=p(1+r/100)^n
where:
A=future amount
p=principle
r=rate
n=time
From the question:
A=£8000, r=5%, n=3
thus plugging the values in the formula and solving for p we get:
8000=p(1+5/100)6n
8000=1.157625p
thus
p=6910.700
Hence the smallest amount is £6910.70~£6910
