12 pack for $3.50

vlada-n [284]

The savings per unit between the best deal and worst deal is about $0.06

$\texttt{ }$

<h3>Further explanation</h3>

Let's learn about the basic formula about Profit and Loss

$\texttt{Profit = Selling Price - Cost Price}$

$\texttt{Selling Price = Cost Price ( 100\% + Profit\% )}$

$\texttt{Loss = Cost Price - Selling Price}$

$\texttt{Selling Price = Cost Price ( 100\% - Loss\% )}$

<em>Let us tackle the problem !</em>

$\texttt{ }$

<em>12 pack for $3.50 → 144 pack for </em> $\$ 3.50 \times \frac{144}{12} = \$ 42$

<em>24 pack for $6.00 → 144 pack for </em> $\$ 6.00 \times \frac{144}{24} = \$ 36$

<em>36 pack for $8.50 → 144 pack for </em> $\$ 8.50 \times \frac{144}{36} = \$ 34$

<em>48 pack for $11.75 → 144 pack for </em> $\$ 11.75 \times \frac{144}{48} = \$ 35.25$

$\texttt{ }$

<em>From information above, we can conclude that:</em>

The Best Deal → 36 pack for $8.50

The Worst Deal → 12 pack for $3.50

$\texttt{ }$

<em>The savings per unit between the best deal and worst deal :</em>

$( \$ 3.50 \div 12 ) - ( \$ 8.50 \div 36 ) = \$ (\frac{1}{18}) \approx \boxed {\$ 0.06}$

Simplify the expression. <br> -216) + 3(5 – 4 x 2)

masya89 [10]

Answer:

Step-by-step explanation:

If it's (-216):

(-216) + 3(5 - 4 x 2)

(-216) + 3( -3)

(-216) -9

-225

If it's -2(16):

-2(16) + 3(5 - 4 x 2)

-2(16) + 3(-3)

-32 - 9

which function has an inverse that is also a function? a. g(x) = 2x-3 b. k(x) = -9x2 c. f(x) |x+2| d. w(x) = -20

motikmotik

Answer:

Step-by-step explanation:

A function have the inverse only if it passes the horizontal line test ,

For the given options we need to look for the function which passes the horizontal line test

Option A is g(x)= 2x-3 which is a straight line with slope not equal to 0 so it passes the horizontal line test and hence it will have an inverse which is also a function.

Option B: we need to restrict the domain to get the inverse so the option B is not correct .

Option C : It also fails the horizontal line test .

Option D : Horizontal line so it also fails the horizontal line test .
