so what i'm gonna do is find out how to get about 42 oz by multiplying 10.57,
10.57 x 4 is the closest i got with 10.57 x 4 = 42.28
then i multiplyed 3.48 by 4 to see the price of 4 bags
which was 13.92
so the 42 oz one has the best deal
hope this helps!
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

The solution is the interval -----> (-∞,8)

The solution is the interval -----> [3,∞)
The solution of the system is equal to
[3,∞)∩ (-∞,8)-------> [3,8)
All real numbers greater than or equal to 3 and less than 8
The graph in the attached figure
The value of the equation increases.
6/15 = x/9
x = 18/5 = 3.600
