Answer:
The proof contains a simple direct proof, wrapped inside the unnecessary logical packaging of a proof by contradiction framework.
Step-by-step explanation:
The proof is rigourous and well written, so we discard the second answer.
This is not a fake proof by contradiction: it does not have any logical fallacies (circular arguments) or additional assumptions, like, for example, the "proof" of "All the horses are the same color". It is factually correct, but it can be rewritten as a direct proof.
A meaningful proof by contradiction depends strongly on the assumption that the statement to prove is false. In this argument, we only this assumption once, thus it is innecessary. Other proofs by contradiction, like the proof of "The square root of 2 is irrational" or Euclid's proof of the infinitude of primes, develop a longer argument based on the new assumption, but this proof doesn't.
To rewrite this without the superfluous framework, erase the parts "Suppose that the statement is false" and "The fact that the statement is true contradicts the assumption that the statement is false. Thus, the assumption that the statement was false must have been false. Thus, the statement is true."

sorry :/ im not sureee but they would have sold 20
Step-by-step explanation:
1. 7 gallons of shampoo will last 5 weeks and 1/4 of another week.
2. 16 Gallons of shampoo will last 12 weeks.
Work Shown
----------------------
0.75 (How much per gallon) × 7 (Gallon of shampoo) = 5.25 (Weeks
0.75 × 16 (How much gallons for 12 weeks) = 12 (Weeks.)
