Question

Imani and Esteban each have the same audiobook club memberships. After listening to four audiobooks , whose book cost more?

Answer 1

First let's calculate the cost for Imani.

The membership is $10, and each book costs $5. If Imani listened to 4 books, the cost is:

`\begin{gathered} \text{Cost}=10+4\cdot5 \\ \text{Cost}=10+20 \\ \text{Cost}=30 \end{gathered}`

Now let's calculate the cost for Esteban.

The membership is $16, and each book costs $2. If Esteban listened to 4 books, the cost is:

`\begin{gathered} \text{Cost}=16+4\cdot2 \\ \text{Cost}=16+8 \\ \text{Cost}=24 \end{gathered}`

So Imani's cost is higher.
