<span>8 Pamela is shopping for bottled water at the supermarket. Which is the best buy?
A 1 2-liter bottle for $0.89
1 liter = .89 /2 = $0.445
B 3 1-liter bottles for $1.50
</span> 1 liter = $1.50/3 = $0.50<span>
C 24 0.5-liter bottles for $5.25
</span>1 liter = 5.25 / 12 = $0.4375<span>
D 36 0.25-liter bottles for $4.75
</span>1 liter = $4.75 / 9 = $0.53
answer best buy is C 24 0.5-liter bottles for $5.25

9 Stuart is buying a pair of jeans that regularly cost
$40. They are on sale for 20% off. If the tax rate
is 8%, what is the sale price of the jeans including
tax?
$40 x 0.80 = $32
$32 x (1.08) = $34.56
answer is
B $34.56

Hey there! :)
Answer:
D : [-4, ∞)
R: [-2, ∞)
Step-by-step explanation:
Notice that one end of the graphed function has a closed circle, and one end is a line. We must use specific brackets accordingly:
[ is used for closed points.
( is used for arrows or open circles.
Therefore:
This graph goes from x = -4 towards x ⇒∞. Therefore:
D : [-4, ∞)
The range of this function goes from x = -2 towards y⇒ ∞. Therefore:
R: [-2, ∞)
Answer:
The point that maximizes the objective function is (3,0)
Step-by-step explanation:
we have
Constraints:
Using a graphing tool
The feasible region is the shaded area
see the attached figure
The vertices of the feasible region are
(0,0),(0,1),(1.5,1.5) and (3,0)
we know that
To find the point in the feasible region that maximizes the objective function, replace each ordered pair of vertices in the objective function and then compare the results.
The objective function is
For (0,0) -----> 
For (0,1) -----> 
For (1.5,1.5) -----> 
For (3,0) -----> 
therefore
The point that maximizes the objective function is (3,0)
Answer:
27.59 without tax
Step-by-step explanation:
27.95 with tax
Probability=(number of specific outcomes)/(total number of possible outcomes)
P(!Z)=25/26 as a fraction exact
P(!Z)≈96.2% (approximation to nearest tenth of a percent)
