    a. YES

    b. NO

    Step-by-step explanation:

    On Saturday,

    Querida gave away 416 coupons

    on Sunday

    she gave away about 52 coupons an hour.

    a. Is the number of coupons Querida gave away on Sunday proportional to

    the number of hours she worked that day?

    YES

    because, judging with saturday and sunday data, it can be deduced that

    52 coupon = 1hour

    416 coupon = 8hours = 1day

    b. Is the total number of coupons Querida gave away on Saturday and

    Sunday proportional to the number of hours she worked on Sunday?

    NO

    the total number of coupons Querida gave away on Saturday and

    Sunday is proportional to twice the number of hours she worked on Sunday.

    coupons (sat + sund) = 2 * hours worked on Sunday
