At age 12 patrick weighed 43 kg; at age 14 he weighed 50 kg patrick's age and weight are related.

a) write an equation to represent the scenario
b)write an incorrect way to represent the scenario
c) write a question to go with the scenario
d solve the question using both the correct and incorrect equations. show all steps

We could say that every 2 years, Patrick gains 7 kg (after reaching a certain age under 12) making it
7(y/2) (if y = every year after the age given, and we divide by 2 because it's every 2 years, not one)+w (patrick's weight at the start)= w (weight)

B-  We could say that w(current weight)+100000=b (new weight)

C - If patrick weighed 43 kg when he was 12 , how much would he weigh when he was 20?

D - Using the correct equation, we have 7(20/2-12/2)+43=7(4)+43=28+43=61
Using the incorrect equation, we have 43+100000=100043 kg

Same length is comparing because it’s saying its the same and not different
