maurice puts 130 trading cards in protector sheets. He fills 7 sheets and puts the remaining 4 cards in an eighth sheet. Each of the filled sheets has the same number of cards. How many cards are in each filled sheet?

subtract four from 130, then divide by 7.

1304=126
126:7= 18 
19

18

18

130  4 = 126
126 : 7 = 18 
344
