Question

1. modeling real life you have $25 to purchase apps on your cell phone. each app that you want costs $3.99. describe the numbers of apps you can purchase.

Explanation:

Step1: Set up division

Let $n$ be the number of apps. We use the formula $n=\frac{25}{3.99}$.

Step2: Calculate the quotient

$n = \frac{25}{3.99}\approx6.266$.

Step3: Consider the real - life situation

Since we can't buy a fraction of an app, the number of apps we can buy is the whole - number part of the quotient. So the number of apps $n$ is 6.

Answer:

You can purchase 6 apps.
