W=-3m+205
m=number of months
205= weight at first to start the diet
w=weight
a)
m=0
so;
w=-3(0)+205=205
Answer: Chris weight at the start of the diet 205 pounds
b)
W=-3m+205
The weight lost each month is the number beside "m", in this case is -3 pounds

c)
w=205-45=160

160=-3m+205
-3m+205=160
-3m=160-205
-3m=-45
m=-45/-3=15
