Answer:

$27.25

Explanation:

We must first determine the average balance:

(900 x 30 days) / 30 days = $900

($1,300 x 20 days) / 30 days = $866.67

($100 x 15 days) / 30 days = $50

average balance = $900 + $866.67 + $50 = $1,816.67

now we multiply times APR:

daily balance x APR/12 = $1,816.67 x (0.18/12) = $27.25
