Answer:

Step-by-step explanation:

The question is on finding the principal value

Formulae for simple interest

S.I= P×R/100×T where P is the invested amount of money, R is interest rate and T is time in years

Given that;

Simple interest=$77 , R=7% and T=1.5 years then

S.I= P×R/100×T...................substituting the values given

77=P×7/100 × 1.5

77=P×0.105

77/0.105 =P

$733.33=P
