Hey there :)
We know the formula for simple interest is
I = prt
{ The picture includes what each stands for }
Lehena:Initial amount = $100
Interest rate = 2.5% =
![\frac{2.5}{100} = 0.025](https://tex.z-dn.net/?f=%20%5Cfrac%7B2.5%7D%7B100%7D%20%3D%200.025)
Time = 3 years
I = ( 100 )( 0.025 )( 3 )
= 7.5$
Total = $100 + $7.5 =
$107.5Marty:Initial amount = $100
Interest rate = 2% =
![\frac{2}{100} = 0.02](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B100%7D%20%3D%200.02)
Time = 3 years
I = ( 100 )( 0.02 )( 3 )
= $6
Total = $100 + $6 =
$106How much more than Marty did Lehena receive?= Total Amount of Lehena - Total Amount of Marty
= 107.5 - 106
= $1.5Your answer will be option
B) $1.50
