What is $920.86 rounded to the nearest 100 dollars?
nlexa [21]

Answer:

$920.86 is rounded to $900

Step-by-step explanation:

The 9 is the hundred place, the 2 is the ten place, the 0 is the ones place, 8 is the tenth, 6 is the hundredth.

So nine-hundred and twenty is rounded to 900.

This is because any number that is 5 or below stays the same, so if the 920 is instead 960, you would round the answer to 1000.

So, 920.86 is rounded to 900.

How much money should be deposited today in an account that earns 7% compounded semiannually so that it will accumulate to $12,0
Korvikt [17]

Given rate is = 7% or 0.07

Total amount needed = $12000

Time = 4 years

Here, the  deposit is  compounded semiannually, means twice per year and this gives 8 annual compounding periods in 4 years.

The equation becomes:

P= \frac{12000}{(1+\frac{0.07}{2})^{2.4}}

P = \frac{12000}{1.035^{8}}

Solving it, we get P = $ 9112.93

Hence $9112.93 should be deposited today.
