1) Use the simple interest formula to determine the missing value.

p=$943.72 r=7.5 t=?, i=$141.56

2) A woman borrowed $3000 from a bank for 9 months. A friend was cosigner of the womanwoman's personal note. The bank collected 5 and one half% simple interest on the date of maturity.

a) How much did thewoman pay for the use of themoney?

b) Determine the amount she repaid to the bank on the due date of the note.

3) Determine the simple interest.(Assume 360 days in ayear.)

p=$694 r=0.049% perday, t=12 months

4)Find the simple interest. Assume the rate is an annual rate. Assume 360 days in a year.

p=1050

r= 2.5%

T=3

I=?
