Asked by George

Kate's parents decided it was time to start giving her pocket money. They were not sure how much to give her so they started with $1 for the first week and doubled it every week. How many weeks until Kate gets over $20 pocket money?
Answered by George
week 1: $1
week 2: 2 x $1 = $2
week 3: 2 x $2 = $4
week 4: 2 x $4 = $8
week 5: 2 x $8 = $16
week 6: 2 x $16 = $32

Assuming that you mean what she gets that week, I agree.

could this question also be interpreted as how many weeks until Kate gets over $20 in pocket money total? as in the answer being 5 weeks?
