8. Work BackwardsTommy has some change in his pocket. He received 4 dimes and a nickel as change for a purchase and now has 80¢. How much change did Tommy have to begin with?C + (4 x10) + 5= 8080-40= 35¢

9. Work BackwardsSha-ne-qua had 3 football cards. She bought 5 more packages of cards and now has 23 football cards. If each pack had the same number of cards, how many cards are in each pack?3 + (5 x f)= 2323 -3 = (5 x f)20= 5 x fF=4
