Question

Michelle is buying one Verizon phone for $289 and wants to purchase additional apps for her phone. Verizon sells their apps for $1.99 each.

a.) Write an algebraic expression to describe how much Michelle will spend before sales tax based on purchasing the phone and any number of apps.
b.) Using your algebraic expression, determine how much Michelle will spend if she buys the phone and 8 apps.

A) a.) Total cost = $289 + $1.99x; b.) $304.92
B) a.) Total cost = $1.99x + $289; b.) $289
C) a.) Total cost = $1.99x; b.) $303.12
D) a.) Total cost = $289x + $1.99; b.) $16.92

Answer 1

The algebraic expression for the total cost before sales tax is $289 + $1.99x. If Michelle buys the phone and 8 apps, she will spend $304.92. The correct answer is Option A).

Step-by-step explanation:

To determine the algebraic expression that describes how much Michelle will spend before sales tax on purchasing a Verizon phone and additional apps, we start with the fixed cost of the phone and add the variable cost for apps. The phone costs a fixed amount of $289, and the apps cost $1.99 each. If we let x represent the number of apps purchased, the total cost before sales tax can be expressed as:

Total cost = $289 + $1.99x

Using this algebraic expression to determine how much Michelle will spend if she buys 8 apps:

Total cost = $289 + ($1.99 × 8) = $289 + $15.92 = $304.92

Therefore, the correct answer is Option A).
