Select the formulas that give the amount p in the account after the first period. a.) p=1.005po b.) p=1.02po c.) p=po(0.02/4) d.) p=po(4.02/4) e.) p=po(1+ 0.02/4)

The amount is calculated by the formula
 P=Po(1+r/100)^n, where r is the rate of interest, Po is the principal amount and  n is the interest period.
In this case, r = 0.02, p.a
Therefore, for the first quarter, r= 0.02/4 or 0.005
Hence the amount after the first quarter or period will be
P= 1.005Po    or 
P= Po(1+0.02/4)
Hence, the answer is either a or d
