Answer:

372.95

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    ($1200)            

a =  amount       (?)

r =  interest rate    (7%)

n = time ( no of years)    (4)

A  =  1200   ( 1   +   <u>7 </u>) ^4

                           100                  A = 1200 ( 1 + 0.07) ^4

A = 1200 ( 1.07)^4   ,    A = 1200 ( 1.31079)

A = 1,572.95

WE now find compound interest with the formula:  

C =  AMOUNT - PRINCIPAL =  $1,572.95  - $1200

    C  =   372.95
