Answer:
value of A is $520
Explanation:
Calculate the amount 'A' by using formula:-
A = P ( 1 + r * Y )
Where A is amount, P is principle , r is rate of interest and Y is time in years
Now, put the given values in A = P ( 1 + r * Y ) to get the value of A.
Since, P= $250, r= 7.2% and Y= 15
r = 7.2% so r = 0.072
A = P ( 1 + r * Y )
A = $250 ( 1 +0.072 * 15 )
A = $250 ( 1 + 1.08 )
A = $250 ( 2.08 )
A = $520
Hence, value of A is $520
