Hey there :)
We know the formula for simple interest is
I = prt
{ The picture includes what each stands for }
Lehena:
Initial amount = $100
Interest rate = 2.5% =
Time = 3 years
I = ( 100 )( 0.025 )( 3 )
= 7.5$
Total = $100 + $7.5 = $107.5
Marty:
Initial amount = $100
Interest rate = 2% =
Time = 3 years
I = ( 100 )( 0.02 )( 3 )
= $6
Total = $100 + $6 = $106
How much more than Marty did Lehena receive?
= Total Amount of Lehena - Total Amount of Marty
= 107.5 - 106
= $1.5
Your answer will be option B) $1.50

Answer: second option
Step-by-step explanation:
To find the inverse function of the given function f(x):
You need to:
Substitute into the function:
Now, you need to solve for "x", to do this, you must divide both sides of the function by 2:
Now, replace "x" with "y" and replace "y" with "x":
Therefore, substituting you get:
