Consider a cookie recipe in which 1 1/2 cups of chocolate chips are needed to make 25 cookies. Lara wants to double the number of cookies. How many cups of chocolate chips should she use?

Juan ate 1/3

Jelly beans remaining = 1 - 1/3 = 2/3

Maria ate 3/4 of the remaining = 3/4 x 2/3 = 1/2

Jelly beans remaining = 2/3 - 1/2 = 1/6

1/6 of the jelly beans = 10 

Total number of jelly beans = 10 x  6 = 60

Answer : There are 60 jelly beans in the bag at first.
