## Question:

Iris has 120 songs on her playlist. each week, she downloads 4 new songs. Write an expression to show the total number of songs on Iris’s playlist after ‘w’ weeks.. (Help please!)

## Answer:

The **expression** that shows the total number of **songs **on** Iris playlist i**s **120 + 4w**

A **linear expression** is an** expression** that has only one variable. The single variable is raised to the power of 1. An example of a **linear expression** is x + 10

**Iris** already has **120 songs** on her **playlis**t. She increases her **playlist **every **week **by **four songs. **

This means that each** week,** her **playlist **increases by 4. This can be represented with the **expression** : 4 x w = 4w

Where **w** represents the number of **weeks.**

In **week** 10, her** playlist i**ncreases by: 4 x 1 = 4 **songs **

In **week** 10, her **playlist **increases by : 4 x 10 = 40 **songs**

But** Iris** already has **120 songs**

This can be represented with the** expression 120 + 4w**

After 1 **week,** the total **songs** she would have is 120 + 4 = 124 **songs **

After 10 **weeks,** the total** songs** she would have is 120 + 40 = 160 **songs**
