Answer:

$167.50

$1507.50

$134

Step-by-step explanation:

Given that:

Cost of sound system = 1675

APR, = 12%

Down payment = 10%

Number of monthly payments = 12

r = 0.12 / 12 = 0.01

Amount of down-payment :

10% * cost of sound system

0.1 * 1675 = $167.50

Amount to be financed :

$1675 - $167.50

= $1507.50

Monthly repayment :

Using the relation :

A / {[(1+r)^n]-1}/[r(1+r)^n]

1507.5 / (1+0.01)^12-1)/(0.01(1+0.01)^12)

1507.50 / 0.1268/(0.01 * 1.1268)

1507.50 ÷ (0.1268/0.01126)

1507.50 ÷ 11.25

= $134
