You can discard the second and the fourth systems because they do not have the form established from the statement.
The first system produce an obvious result given that is represents an option that is always better than the other 5.5x will be lower than 7.5x + 10 for any positive value of x, and so there is no need to make any comparission.
The third system is
y = 7.5x and y = 5.5x + 10 which need to be solved to determine when one rate is more convenient than the other.
Answer: y = 7.5x and y = 5..5x + 10

70 ounces or 4.375 Pounds. (They weigh the same)
Explanation:
First off all, lets convert everything to improper fractions. Two pounds converted into a fraction would be 2/1. 1 3/4 would be 7/4. After converting the fractions of pounds, we add them. 2/1 + 7/4. Since they have different denominators, we have to find the Lowest Common Multiple which would be 4. Leave the right side alone and multiply 4 to your left denominator and numerator. That would leave you with 8/4 + 7/4. Adding them up, you would get 15/4. Divide that, and you should get 3 3/4 Pounds. Convert that into ounces. (16 ounces = 1 Pound) and you should get 60 ounces. Add the 10 ounces from the sentence and you should get 70 ounces
