the first graph is (x+20)/x
the second graph is x/(x-20)
X = amount of lawns
y = amount of dog walks
25x + 15y = 1975
25x + 15(50) = 1975
25x + 750 = 1975
25x = 1225
x = 49
so x ≤ 49 (this number depends on how much Sarah walks)
y ≥ 50 (is how much Sarah walks)
hope this helps

The answer to your series is 62. I subtract the difference of the last two numbers and add that to the last number
Answer:
$2.72
Step-by-step explanation:
If the price decreased by 20%, the final price will be 100% - 20% = 80% of the inicial price.
So, we can write the ratio box:
Old value New value
Percent value: 100% 80%
Value: $3.40 X
Then we can solve with a rule of three:
100% -> $3.40
80% -> X
X = 0.8 * 3.4 = $2.72
