Answer: 125
Explanation
250x4=1000
1000 divided by 8 = 125
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
