Find the interest rate if £6400 has a final value of £8334 in 3 years. Give your answer to 1 d.p

Mila [183]

Answer:

Step-by-step explanation:

6400(1+i)³=8334

(1+i)³=1.3021875

∛(1+i)³=∛(1.3021875)

1+i= 1.092

i= .092

I guess if you were to round to 1 decimal point it'd be .1

kakasveta [241]

Answer:

-2

Step-by-step explanation:

$y = kx + n$

When you insert the given points you get

$3k + n = 4 \\$

$7k + n = - 4 \\$

Than you multiply the first one by - 1 and sum it with the second to get rid of n

$4k = - 8 \\ k = - 2$
