The correct option is The Barbara equation did not consider the number of bottles of water.
Given,
The selling price of iced tea is $1.49 per bottle.
The selling price of water is $1.25 per bottle.
Equation written by the Barbara,

Here in this question Barbara multiply the selling price of bottle with the number of bottle using the coefficient x, But she did not use any coefficient for the bottle of water. The correct equation is,

where<em> y </em>is the number of water bottle sold to earn the profit of $100.
Hence the correct option is the Barbara equation did not consider the number of bottles of water.

Compute the difference quotient:
(<em>f</em> (4) - <em>f</em> (1)) / (4 - 1) = (-3 - 12) / 3 = -15/3 = -5
I think it is the bottom left
Your question is not clear. I must guess what you meant. Did you mean "Find the two numbers?"
If so, let the two numbers be m and n. Then mn=60 and m=n-7.
Then (n-7)(n) = 60, or n^2 -7n - 60 = 0. This factors: (n+5)(n-12) = 0
Thus, n = -5 or n = 12.
check: does mn = 60? Does 12*5 = 60? Yes. Is m (which is 5) 7 less than n (which is 12)? Yes.
Note that you could also check to see whether n=-5 and m=n-7=-5-7=-12 is also a solution.
