The formula is
A=p (1+r/k)^kt
A future value
P present value
R interest rate
K compounding periods
T time
When the compounding periods are daily balance after one year is
A=1,870×(1+0.197÷365)^(365×1)
A=2,277.06
When the compounding periods are monthly balance after one year is
A=1,870×(1+0.165÷12)^(12×1)
A=2,202.99
So will save
2,277.06−2,202.99
=74.07....answer
Hope it helps!
