Answer: C) Tracy spends $7 every 4 days
Graphing the function as well as x = 4 will show that there is a difference in the y-value of 7 between x=0 and x=4, meaning she spends $7 every 4 days.

Answer:
m = (c-2)/(a+b)
Step-by-step explanation:
am+ bm= c-2
Factor out m
m( a+b) = c-2
Divide each side by (a+b)
m( a+b) /(a+b)= (c-2)/(a+b)
m = (c-2)/(a+b)
So the total for dogs (bottom left box) is 47
17 of them had a cat so the top left box is 17
47-17=30 so 30 have a dog but no cat (left column, middle row)
24 cat but no dog (middle column, top row)
9 no cat no dog (very middle box)
Total no dog= 24 + 9 = 33
Total cat (top right) = 17 + 24 = 41
Total no cat (right column, middle row) = 9 + 30 = 39
Hope this make sense :)
