Answer:
(6,-5),(7,-3),(8,-1),(9,1)
Step-by-step explanation:
a function cannot have two inputs for the same output as a(with 3),b(with9), and c(with5) have two output for 1 input ,they are not functions
The first deal is better because it has more balloons for not too much of a price (individually)
15*4= 60
60/18= 3.33
Deal 1= 3.33 for each balloon
10*5= 50
50/16=3.125
caca
caca con caca e caca en bolas
The answer would be 1.25.
