For the first one you form an equation so £3000 x i^4 = £3690.37 then rearrange to make i the subject by doing 3690.37/3000 all root 4 and you should get 1.05... then round to 1dp and you should get 1.1%

I’m not 100% sure abt this q but I think the same concept still applies so do 710.89/658.20 and root all of this by 3 (since you’re only working out the interest between the second and fifth year) so the answer should be 0.47... = 0.5% to 1dp

That’s wrong

I got those same answers
Idk what is wrong

ok right so this is partially correct
however if we think about multipliers
we r saying that i here would be a multiplier
so an increase of 2% each year is 1.02^n
so how can we convert that multiplier of 1.05.. to a percentage increase?
You can simply just look and convert or do (1.05.. * 100) - 100

My bad I tried

Ohh yeah thank you

Does the vid help?
cloud mountain
but what is the answer?
No clue i’d know how to do it if they had told us the interest rate like how the person above explained but idk how to do it when they’ve given the final amount with interest

Does the vid help?
not at all
lol i rewatched it a thousand times
i got the same answer u got
cloud mountain
lol i rewatched it a thousand times
I just watched the vid and clocked what we did wrong
Basically
After you get like 1.0531...
Multiply it by 100 to get %
So you’d get 105.3142...

Any1 good with circle theorems help me fr

Minus it by 100 you get 5.314...
Then round that to 1dp you get 5.3%
That should be the correct answer for the first one

Ok
YES
ITS CORRECT
i love you bro
but now i need help solving the second one
<@&791435371564892232>
can u solve the second one
cloud mountain
i love you bro
yw and I’m a girl 😭
cloud mountain
Same concept the answer should be 2.6%
cloud mountain
I’m not 100% sure abt this q but I think the same concept still applies so do 71...
Do this and after you’ve cube rooted it multiply by 100 then minus 100 and then round to 1 do

yesss
