I\'m having trouble with a couple questions. Please show work so I can understand. Thanks!

If you deposit $3,000 at the end of every quarter in a savings account that pays a nominal APR of 6% per year, compounded weekly, how much will you have at the end of a year? O $12,275 O $12,895 O $13,785 $14,897

Solution

quarterly rate = (1 + 6%/52)¹³ - 1 = 1.51%

N = 4, PV = 0,PMT = 3000, rate = 1.51%

use FV function in Excel

amount at the end = 12,275

b. effective rate = 1.0265^12 - 1 = 36.87%
