Answer:
As per the statement:
Mr. Mendez had 24 cows on his farm.
⇒He had number of cows on his farm = 24 cows.
At an auction, he bought 5 more cows
Change in number of cows = 5
We have to find the percent of change in the number of cows on the farm.

Simplify:

Therefore, the percent of change in the number of cows on the farm (to the nearest tenth) is 20.8%
I am doing with Question Number 2
Let the two numbers be 'x' and 'y'.
According to the question, the product of two numbers is 14.

So, xy=14 (Equation 1)
Now, one of the numbers is 3 ½ times the other.
So, 
(Equation 2)
Substituting the value of 'x' from equation 2 in equation 1, we get



So, y= 2 and -2
So,
and 
x=7 and -7
Numbers are 2,7 and -2,-7.
Sum of numbers 2 and 7 = 9
Sum of numbers -2 and -7 = -9.
