*if u have time on ur hands at good at word problems PLEASEEE HELP*

Tiffany and Erin both need to sign up for a new cellphone service plan. They’ve researched a variety of different cellphone companies and have narrowed it down to two, AT&T and Verizon. AT&T charges a one-time registration fee of $15.00 plus a monthly fee of $35.00. Verizon, however, charges $25.00 per month plus a registration fee of $75.00.

Part A: Build a function using () for AT&T () for Verizon that will represent both service plans (3 pts).

· AT&T:

· Verizon:

· What does each variable represent in the context of this situation?

Answer 1

`AT \alpha T() = R_(f) \: + \: M_(f)`

`Verizon() = R_(f) \: + \: M_(f)`

`R_(f) =one \: time \: registration \: fee \: \\ M_(f) = monthly \: fee`

Explanation:

AT&T charge fee = $15.00 + $35.00

Verizon charge fee = $25.00 + $75.00

then the function for AT&T is:

`AT \alpha T() = R_(f)(15) \: + M_(f)(35)`

and the function for Verizon is:

`Verizon() = R_(f)(25) \: + M_(f)(75)`

where:

`R_(f) =one \: time \: registration \: fee \: \\ M_(f) = monthly \: fee`
