Answer:
G.
Step-by-step explanation:
cards = 2
dollars = 9
to check that the number of cards with the correct amount d;
use the ratio and proportion.
(3 x 18)/9 = 4
(4 x 31.5)/18 = 7
(7 x 45)/31.5 = 10
therefore, option G. table G. is the correct answer
try doing the ratio and proportion on the other table and the number of cards DO NOT match with the amount. (see attached)

Ab=750 and a=b-5, using this value of a in the original equation gives you:
(b-5)b=750
b^2-5b=750
b^2-5b-750=0
b^2-30b+25b-750=0
b(b-30)+25(b-30)=0
(b+25)(b-30)=0
b=30
