total amount to be paid = $19.5
step-by-step explanation:
given ,
original price = $25.99
discount = 25%
discount amount = 25% of original price
discount amount = 25/100 * 25.99
discount amount = $6.49
hence , the total amount to be paid = original price - discount amount
= $25.99 - $6.49
=$19.5
total amount to be paid = $19.5
