Answer:

a. 90 pack

b. $0.27

c. $0.18

d. $0.21

e. 60 pack

Step-by-step explanation:

a. i think the 90 pack container should be having least unit rate per pack,as purchasing in bulk amount the cost of a unit should be reduced to some amount which is must to lure the customer to purchase in bulk amounts.

b. unit price = total cost of container ÷ number of individual units inside it

for 20 pack, unit rate = 5.49÷20 = $0.27

c. for 60 pack, unit rate = 10.97÷60 =$0.18

d. for 90 pack, unit rate = 18.95÷90 =$0.21

e. ∴ the 60 pack container has the least unit rate per pack which is in contrary with our expectation of 90 pack to be lowest expecting bulk order.

What is the limit of f (×) as x approaches - infinty

tatyana61 [14]

If the degree of numerator and denominator are equal, then limit will be leading coefficient of numerator divided by the leading coefficient of denominator.

So then the limit would be 3/1 = 3.

Alternatively,

$\displaystyle \lim_{x\to\infty}\dfrac{3x^2+6}{x^2-4}=\displaystyle \lim_{x\to\infty}\dfrac{3x^2+6}{x^2-4}\cdot\dfrac{1/x^2}{1/x^2}=\lim_{x\to\infty}\dfrac{3+\frac6{x^2}}{1-\frac4{x^2}} = \dfrac{3+0}{1-0}=\boxed{3}$

Hope this helps.

Step 1: Define

Identify

25p + 1t = 51

Step 2: Solve for t

[Subtraction Property of Equality] Subtract 25p on both sides: 1t = 51 - 25p
Simplify: t = 51 - 25p

5 + 6 - (-3) - 8 + 4 -3

Komok [63]

Okay, so -

We have one very important thing here. This little part 6 - (-3). 

Now, it's essential to remember that when we have two negatives like this, we simply draw a line straight down. It becomes a positive!

So, our question is essentially 5 + 6 + 3 - 8 + 4 - 3 = ? instead of 5 + 6 - (-3) - 8 + 4 - 3! =)

With that in mind, we simply solve left to right.

11 + 3 - 8 + 4 - 3 = ?

14 - 8 + 4 - 3 = ?

6 + 4 - 3 = ?

10 - 3 = ?

7 is our final answer! =)
