Linear models are a part of everyday life, but many times they are not easily visible. They can be easily related to our life experiences. Read each of the three scenarios below to see how linear models show up in our lives and how we can use them to make decisions. Answer the related questions.

1) Marco and his two younger sisters would like to purchase a silver charm bracelet for their mothers 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.Function:Y=Mx+bF(x)=Mx+bF(x)=15x+85Reason for choosing functionThe reason for me picking this function is that it applies to how many charms she has to buy plus the standard price of 85 dollars. So it depends how charms she buys times fifteen plus 85 dollars because of the bracelet without charms.

What would be a reasonable domain for this function based on this scenario? Explain why this is a proper domain.Domain:x is greater than or equal to ________

and x is less than or equal to________

_________>=x
