If Jane has 23 cats and I have 2 cats, and then Jane gives me 5 cats, how many more cats does Jane have than I? Rhonda has 12 marbles more than Douglas. Douglas has 6 marbles more than Bertha. Rhonda has twice as many marbles as Bertha has.

11 cats

Step-by-step explanation:

Given :

Jane's initial = 23

My initial = 2

Jane gives out 5 cats to me ;

Jane's new = 23 - 5 = 18

My new = 2 + 5 = 7

Number of cats Jane has than me :

Jane's new - My new

18 - 7 = 11 cats
