Answer:
59 marbles.
Explanation:
Let's call the number of marbles Jessie has "x".
We know that:
x > 50
x < 100
x % 10 = 3
x % 6 = 1
We can start by finding the possible values of x that satisfy both x % 10 = 3 and x % 6 = 1.
Starting from x = 53:
x = 53 satisfies x % 10 = 3 but not x % 6 = 1
x = 59 satisfies both x % 10 = 3 and x % 6 = 1
So, Jessie has 59 marbles.
