1) Mark and Huong are selling flower bulbs for a school fundraiser. Customers can buy packages
tulip bulbs and packages of crocus bulbs. Mark sold 9 packages of tulip bulbs and 1 package of
crocus bulbs for a total of $127. Huong sold 6 packages of tulip bulbs and 6 packages of crocus
bulbs for a total of $186. Find the cost each of one package of tulips bulbs and one package of
crocus bulbs.

Answers

Answer:

Package of tulip bulbs = $12

Package of crocus = $19

Step-by-step explanation:

Let b = cost of a package of bulbs

     c = cost of a crocus package

Mark:   (1)   9b + c = 127          Huong:  (2)   6b + 6c = 186

                          c = 127 - 9b                        6b + 6(127 - 9b) = 186

                                                                      6b + 762 - 54b = 186

                                                                                      - 48b = -576

                                                                                           b = 12

                          c = 127 -9(12)

                          c = 127 - 108 = 19

Mrs. Leary wants to buy some plants and potting soil. Each plant costs $2.50 and each bag of potting soil costs $3.25. Mrs. Leary wants to spend no more than $50. If Mrs. Leary buys 4 bags of potting soil, which inequality represents the number of plants, p, that she may buy?

Answers

Answer: Ok while i was working out this problem I started by multiplying so i started by 5

2.50 x 5 = 12.5

3.25 x 5 = 16.25 then I added then and got 28.75. So i was like i should go higher. I picked 7.

2.50 x 7 = 17.5

3.25 x 7 = 22. 75 then I added those two and got 40.25 when i got that I was like yes, Im getting closer. So i picked 9 then I got..

2.50 x 9 = 22.5

3.25 x 9 = 29.25 and that equaled 51.75

so then i was like oh! Taxes so I think the answer might be 8. 46 plus tax lol.

The population of a town is 75 000 and decreases 15% each year. Complete the exponential function that models the population afterx years
f(x) = 75,000

Answers

Answer:

Step-by-step explanation:

This is an exponential function of the form:

[tex]y=a(1-r)^x[/tex] where a is the initial value and (1 - r) is the growth rate (which in our case is a decay, actually!). Our initial value is 75000 and our rate of change in the population is 15% or .15. Filling in our model:

[tex]y=75000(1-.15)^x[/tex] and simplifying:

[tex]y=75000(.85)^x[/tex] This turns out to be a decay problem because the value inside the parenthesis is less than 100%.

x is our time, so the model is as stated above.

Consider the system of equations 3x + y = 10 and 6x – y = 17 . What is the value of the x-coordinate of its solution?

Answers

Answer:

x = 3

Step-by-step explanation:

These are simultaneous linear equations hence, we add them because +y and -y will cancel eachother.

3x + y = 10

6x - y = 17

____________

9x        = 27

  x         = 27/9

  x         = 3

So, x- coordinate is 3

Answer: the answer should be x = 3

Step-by-step explanation:

A sales team estimates that the number of new phones it will sell is a function of the price that it sets. It estimates that if it

sets the price at x dollars, it will sell f(x) = 4,920 - 6x phones. Therefore, the company's revenue is x . (4,920 - 6x). Find

the price x that will maximize the company's revenue.

Answers

Answer:

410

Step-by-step explanation:

Revenue is given by the relation :

x . (4,920 - 6x)

F(x) = 4920x - 6x²

To obtain the price, x which maximizes revenue, we take the first derivative of the revenue function and equate to 0

F'(x) = 0

F'(x) = 4920 - 12x

4920 - 12x = 0

-12x = - 4920

x = 4920 / 12

x = 410

Price will be 410
