Question

Matt has 80,000 in a savings account. The interest rate is 12% pre year and is not compounded. How much will he have in 4 months

Answer 1

Matt will earn 3,200 interest in 4 months.

Given:
principal : 80000
interest rate : 12%
term : 4/12  *4 months in a year

Simple Interest = Principal x Interest rate x term

S.I. = 80000 x 12% x 4/12
      = 9600 x 4/12
S.I. = 3,200

OR
12% ÷ 12 month = 1% per month

S.I. = 80000 x 1% per month x 4 months
S.I. = 800 x 4 months
S.I. = 3,200
