#### Answer

Yen must replay $\$37,638$ in total.

#### Work Step by Step

We look up the column "4 years" and the row "3.5% interest" in the table. This gives us the value "1.1475". We multiply the principal ($\$32800$) by this number:
$32800*1.1475=\$37,638$
Therefore, Yen must replay $\$37,638$ in total.
