Where do we find the answer from?
Answer: The interest is: " $ 64 .00 " .
_____________
Step-by-step explanation:
_____________
Take note of the formula:
" Ⅰ = Prt " ;
→ that is:
_____________
→ " Ⅰ = P * r * t " ;
_____________
In which:
_____________
" Ⅰ = the interest " ;
" P = the Principal amount of money " ;
" r = rate " (expressed as the "decimal form" of the percentage) ;
" t = time " (in years) ;
_____________
We are given:
_____________
P = $400 ;
r = 0.08 ;
{<u>Note of interest</u>: That is " 8% " ; since "8 % " = "(8/100)" ;
= "(8 ÷ 100)"
= " 0.08 ".}.
t = 2 ; {that would represent: " 2 (two) years".}.
_____________
We are to solve for "Ⅰ" ; the amount of "Ⅰnterest" :
→ To solve for "Ⅰ " ; we plug in our given values; and calculate:
_____________
→ Ⅰ = P * r * t ;
= 400 * 0.08 * 2 ;
= 64 .
_____________
→ Ⅰ = $ 64.00 .
