Answer:

Interest (I) = $18

Step-by-step explanation:

$15,000 by the end of grace period

$2,500 payment was made by the 3rd day

$15,000/$2500=6

6×3=18

I = PRT/100

I = (15,000 × 20% × 18 days)/100

I = {15,000 × 0.2 × (18/30)}/ 100

I= {15,000 × 0.2 × 0.6}/ 100}

I= {1800}/ 100}

I= {18}/ 1}

Interest (I) = $18
