SOLUTION: 1.How much would Php. 10,000,000 amount in 5 years at 16% interest rate and compounded quarterly? 2. Mr. Cruz deposited money 500 pesos in the bank which earns 5% annual interes

A = P(1 + )nt

A = final amount = ?
P = beginning amount = 10,000,000
r = interest rate expressed as a decimal = 0.16
n = the number of compoundings each year = 4 (quarterly)
t = the number of years = 5

A = 10000000(1 + )(4)(5)
A = 10000000(1 + 0.04)20
A = 10000000(1.04)20
A = Php 21911231.43

---------------------------------
    

A = P(1 + )nt

A = final amount = ?
P = beginning amount = 500
r = interest rate expressed as a decimal = 0.05
n = the number of compoundings each year = 1 (compounded annually)
t = the number of years = 2

A = 500(1 + )(1)(2)
A = 500(1 + 0.05)2
A = 500(1.05)2
A = Php 551.25
