Jenny has nine marbles, but her best friend Susie gives her ten more! However, the neighborhood bully, Danny, steals four marbles from her. Jenny's marbles are all of very high quality, so she trades each of her marbles for three of John's marbles apiece. The very next day is Jenny's birthday so she receives seven marbles from her parents, and finally gives two to her sister. How many marbles does she have now?

Sagot :

Answer:

50

Step-by-step explanation:

she starts with 9 plus the 10. so she has 19. Danny takes 4 so she has 15. then she trades so she gets 3 per marble she trades so it's like 15 times 3 which is 45. plus the 7 her parents gave her which is 52 and she gives 2 to her sister. so it's 50
