Question

I asked this question an hour ago, no one helped me, I asked again here, no one is helping. Can someone just please HELP?!?!?!

Answer 1

Marco and his two younger sisters would like to purchase a silver charm bracelet for their mother’s birthday. They went to the mall and found what they were looking for at Store A. In Store A, the bracelet without charms costs $85 and each charm costs $15.

Use function notation that models the total price of the bracelet and how that price is based on the number of charms. Explain the reasoning behind your equation.

Answer 2

This is my answer : f(x) = 85 + 15(x)

Answer 3

i can try

Answer 4

Just wanted to know if I'm correct

Answer 5

i need to tell you one thing that im not that good in word problems but i think your right i would get other peoples opionins because im horrible at word problems

Answer 6

lol thats okay :)

Answer 7

im sorry but i do think you might be right im doing rates and im trying to figure those out

Answer 8

@ganeshie8

Answer 9

this question has different parts so.. I need help with multiple things

Answer 10

What would be a reasonable domain for this function based on this scenario? Explain why this is a proper domain.

Answer 11

Yes, you are correct :)

Answer 12

okay, but what is the domain?

Answer 13

Since a bracelet with no charms would be $85 and each charm adds an additional $15.

Answer 14

The domain would be the set of all x values you can use in your function. Since x stands for the number of charms, could you have zero charms?

Answer 15

Well yeah if they choose not to have any charms.

Answer 16

Could you have a negative number of charms?

Answer 17

No

Answer 18

Right, so you know that x has to be greater than or equal to 0. Is there any upper limit on the number of charms you can buy?

Answer 19

So we can say that x > 0 right? would that be the domain?

Answer 20

x greater than or equal to 0. :) Yes, that would be the domain.

Answer 21

ok thanks! but there is more..

Answer 22

If Marco and his sisters have saved $250, make a graph to show all of the charms they could purchase with a bracelet if they had saved between $85 and $250.

Answer 23

Ok :) If you draw a graph I will give feedback on it. :)

Answer 24

should it look something like this?

Answer 25

Yes, although you may want to change the scale of your y axis so that you can show cost up to $250

Answer 26

I can't change the graph, the program wont let me but they said I can write it in words so this is how I wrote it


Origin from y-axis = 85 Origin from x-axis = 0
y-axis intervals = 5 x-axis intervals = 1

Answer 27

Marco found five charms that he likes. Using your function, determine the cost of the bracelet he would make.
f(x) = 85 + 15(5)
f(x) = 85 + 75
f(x) = 160 He would spend 160 dollars on the bracelet.




Is this correct?

Answer 28

That labeling of your graph should work :)

Answer 29

okay thanks, but there is a part 2 of this question :(

Answer 30

Yes, I am bouncing back and forth ... sorry! Looking at part 2 now

Answer 31

And yes, that is correct. Good :)

Answer 32

Now for the graph, what do you have?

Answer 33

i couldnt make the graph cuz the program is complicated but this is the description of it..


Origin from y-axis = 85 Origin from x-axis = 0
y-axis intervals = 5 x-axis intervals = 1


gonna send you the part 2 now.. one minute

Answer 34

Your description of the labeling of the graph sounds good. Just a moment, please, I am also going to include a drawing.

Answer 35

Marco is wondering from which store he should buy the items so that he spends the least amount of money. Which store should Marco use if he wanted the five charms and silver bracelet all together? What advice can you tell Marco to help him shop wisely depending on the number of charms he wants to buy? Justify how you reasoned your answers.

Answer 36

Ok. :) What do you think for this part?

Answer 37

Store A
f(x) = 85 + 15(5)
f(x) = 85 + 75
f(x) = 160

Store B
f(x) = 100 + 12(5)
f(x) = 100 + 60
f(x) = 160
