Question

PLEASE HELP

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.

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

Answer 1

I think i have the first part down
p+85=15x

Answer 2

p represents the price
x represents the nimber of charms

Answer 3

you almost got it

Answer 4

f(x) = 15x + 85

Answer 5

oh thats right function notation

Answer 6

mhm

Answer 7

do you understand the reasoning behind this?

Answer 8

no

Answer 9

so you have a basic value of 85 because that's how much a bracelet cost and that value or price cannot change, but because you can have multiple charms we put in a 15 times x. X stands for the number of charms we buy but we don't know how many and this value can change so that is why we put in an x
