Answer:
the one with 12, 18, 22
Step-by-step explanation:
in the first one, 9-3=6 and 6-3=3 so -3 is the constant of the proportionality
in the second one 3-1=2, 2-1=1 so here the constant of proprtionality is -1
in the third one 16+2=18, 18+2=20 so the constant of proportionality is 2
fourth one 4 + 0.5= 4.5 and 4.5+0.5= 5, constant of proportionality is 0.5
fifth one 12+6=18, but 18+6=24
and the rest are all proportional
A. C=.55p so if p=2, then it would cost $1.10.
B. so since theyre reducing the cost by five cents then the cost per pound is 50 cents so c=.50p and the cost of 2 pounds would be a dollar.
