Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Amanda needs 12 more marbles to have twice as many marbles as Katrina, and Mabel has 5 times as many marbles as Katrina. If Mabel has 85 marbles, how many more marbles does Mabel have than Amanda?

### Response:
 Katrina ana mabulinge 85/5 = <<85/5=17>>17.
Mabulinge mara mbili ya Katrina ni 17 x 2 = <<17*2=34>>34.
Amanda anahitaji mabulinge 12 zaidi ili awe na mabulinge mara mbili ya Katrina, hivyo ana mabulinge 34 - 12 = <<34-12=22>>22.
Mabel ana mabulinge 85 - 22 = <<85-22=63>>63 zaidi ya Amanda.
