On Monday 100 books were returned to the library. On Friday 4 times as many books were returned to the library as books that were returned on Monday. 

 

Which set of equations can be used to find b, the total number of books returned to the library on these two days?

• 100 x 4 = 400

  400 x 4 = 1,600

  400+1,600=2,000

• 100 x 4 = 400

  400 + 100 = 500

• 100+4= 104

  104 x 4 = 416

  104 + 416=520

• 100-4=96

  96-400=304
