Ed is on a road trip. he has already traveled 242 miles and is driving at a rate of 63 miles per hour. which equation could be used to find how many hours, x, ed has left in his road trip if he is traveling 668 total miles?
a.
242x + 668 = 63

b.
242x + 63 = 668

c.
63x + 242 = 668

d.
63x + 668 = 242

C

Step-by-step explanation:

Ed is traveling at 63 miles per hour so it will have a variable. He already drove 242 miles, and is planning to drive 668 miles. Because the goal is 668, this whole equation equals 668.

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
