$800 at 7% compounded annually for 2 years
Marina86 [1]

Answer:

$115.92

Step-by-step explanation:

To calculate compound interest, which Amount - Principal but we dont know the value for amount so we find the amount first by using the formula.

               A =  P ( 1 +   <u>R</u> ) ^n

                                 100      

where p = principal    ($800)            

a =  amount       (?)

r =  interest rate    (7%)

n = time ( no of years)    (2)

A  =  800   ( 1   +   <u>7 </u>) ^2

                          100                  A = 800 ( 1 + 0.07) ^2

                                                  A = 800 ( 1.07)^2   = 800 ( 1.1449)

A = 915.92.

We then find compound interest with:    

C = Amount - Principal   =   $915.92  -  $800    =    $115.92

The temperature in the late afternoon
Fantom [35]

Answer:

-7.5 - (8.5 + 5)

Step-by-step explanation:

We just add together the values of how much it dropped at different parts of the day, and subtract them from what we started with. The parenthesis are important cause we want to know what the total temperature drop for the day was before we subtract it to get the actual temperature we end up with.
