Idon't understand this question. can you guys ?

a carnival has two payment options. plan a, you pay $10 admission plus $3 for each ride. plan b, you pay a $20 admission plus $1 for each ride. write an inequality that would express the situation where plan b is the best buy.
a) 20x > 10 + 3x
b) 20x < 10 + 3x
c) 20 + x < 10 + 3x
d) 20 + x > 10 + 3x

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

what is the your question?
