not sure what this means, because my problem asks to choose which are true, but it seems like it wants an explanation? 

if so, here's what i got

a) by age 14, sean consumed 400 cans of cola

b) sean consumed 50 cans of cola by the time he was 6

c) at 12 years old, sean was consuming about 50 cans of cola per year

d) when sean consumed 450 cans of cola, it took about one year to consume another 70 cans

**do those look right??/

but which would be true or as the problem asks? :/
