Answer 1

$90.12

Explanation:

The principal amount of the loan is ...

(sale price)(1 + sales tax rate) - (down payment)

= $19,725×1.0475 -2175 = $18,486.94

For a secured loan, the APR charged for an average credit rating appears to be 5.85%, so the interest for the first month is ...

i = Prt = ($18,486.94)(0.0585)(1/12)

i = $90.12
