The formula for simple interest is A=P(1+rt) where:
A=The money accumulated
P=The original money borrowed
t=time (in years)
Plug in the values we know
5013=P(1+(.037*4.576923)) Change 3.7% to a decimal, moving it over two spaces to the left; Change 238 weeks to years by taking 238/52(weeks in a year)=4.576923 years
P= 4287.01 Solve
$4287.01 is what Miley paid in interest.
