If Sam deposit $x with r% simple interest then the principal will grow after 4 years to
Again, for the second year $x investment with r% simple interest will grow to .
Now, the third year $x investment with r% simple interest will grow to

Therefore, the total sum becomes
=
=
So, in case of Sam the sum will be = = $53750
