2. Ms Ho numbered thirty pupils by writing 1, 2, 3, … , 28, 29 and 30 on their name tags.

(a) How many digits did she write in all?

(b) She arranged all the thirty pupils to stand in a row, starting from Number 1 to Number 30.  Next, for every second pupil, she asked each pupil to sit.  Then, for every third pupil, she asked each standing pupil to sit and each sitting pupil to stand.  She followed the same pattern (which is to ask each standing pupil to sit and each sitting pupil to stand) for every fourth pupil, every fifth pupil, and so on till the 30th pupil.  How many pupils were standing after the whole process was completed?

    For question 1, Carrie has $7.10.

    Amy has 6 coins, $1.2 in value
    Brenda has 9 coins.
    Carrie has 6+3+7 coins.
    31-6-3-7=15
    15 coins = $7.5
    Each coin = $0.50

    Carrie – (0.50×6) +(3×0.50)+$2.60 = $7.10

    Question 2a

    1-9. 9 digits
    10-19 20 digits
    20-29. 20 digits
    30. 2 digits
    Total. 51 digits

    Question 2b
