    34,860

    Step-by-step explanation:

    In a sample of 32 residence, 24 take Vitamin C. From here we can get the proportion of residents who take Vitamin C, which is 24/32 = 3/4 = 0.75

    0.75 in percentage is 75%. This means 75% of the residents in sample take Vitamin C.

    We can expect the same percentage of people in entire population to take Vitamin C.

    Total population of city = 46480

    Expected number of residents who take vitamin C in the city = 75% of 46480

    = 0.75 x 46480

    = 34860

    This means, 34860 is an estimate of number of city residents who take Vitamin C supplement daily.
