Sagot :

Exercise data

$ 1500

Interest rate = 0.07%= 0.07/ 100 = 0.0007

a) How much interest will Arielle pay for the statement for the month of May which

has 31 days?

Simple Interest=P×I×N

where:

P=principle

I=daily interest rate

N=number of days between payments

Interest= 1500 x (0.07/100) x 31 = $ 32.55

another way to write

Interest= 1500 x (0.0007) x 31 = $ 32.55

b)What is the balance that she owes?

Balance = P x ( 1 + I*t) where t= time.

Balance = 1500 x (1 + 0.0007*31)

Balance = 1500 x (1 + 0.217)

Balance = 1500 x (1 .217)

Balance = 1532.55

another way to solve

Balance = P + Interest

Balance = 1500 + 32.55

Balance = 1532.55
