Answer:
$733.33
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
