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

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
