Answer: the answer to this is 9/10
Step-by-step explanation:
1/3 is the ratio of cups of water to cups of flour as a fraction (simplified)
For this case we have two options:
Option A:
Tomato juice, 48 oz. can for $ 2.49.
The unit price is:
(2.49) / (48) = 0.05 cents per oz.
Option B:
Tomato juice, 6-pack of 10 oz. cans for $ 3.99.
The unit price is:
(3.99) / (6 * 10) = 0.07 cents per oz.
Answer:
The best buy would be:
Tomato juice, 48 oz. can for $ 2.49.
we are given
f(x)=[x=1]
where bracket means ceiling functions
we know that
Ceiling function returns the least value of the integer that is greater than or equal to the specified number
so, we can check each options
option-A:

At x=-4:
f(x)=[-4-1] =-5
For x<-3:
Let's assume
x=-3.1
f(x)=[-3.1-1] =[-4.1]=-5
so, this interval is TRUE
option-B:

At x=-2:
f(x)=[-2-1] =-3
For x<-1:
Let's assume
x=-1.1
f(x)=[-1.1-1] =[-2.1]=-3
so, this is FALSE
