How much money will you have in 8 years if you invest $4000 at 3.5 compounded quarterly?

I assume that means 3.5% annual interest.

Each quarter we multiply our money by

Eight years is 32 quarters.

So after eight years we have

That's compared to $5120, principal plus simple interest of just 8(3.5%)=28% of 4000.

$5286.08

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

the answer is 31.27mph
