Answer:
1) Yes, 1/2 and 2
2) b=1/2 × t
t=2 × b
Step-by-step explanation:
1) Yes, because every package of a toy equals 2 batteries. The constant of proportionality is 1/2 and 2 because 1 ÷ 2 = 1/2 and 2 ÷ 1 = 2 (amount of toys divided by amount of batteries and vice versa)
2) b = 1/2t, because for every battery, there is 1/2 a toy.
t = 2b, because for every toy, there are 2 batteries
note: you can't actually have 1/2 a toy, but we write it like that for the sake of showing the relationship of toy to battery.
