Question

1. each runner is carrying an 8 - ounce bottle of water, a 2.1 - ounce energy bar, and a 3 - ounce energy drink. write an expression in simplest form that represents the weight carried by y runners. interpret the expression.

Explanation:

Step1: Find the weight carried by one runner

One runner carries an 8 - ounce bottle of water, a 2.1 - ounce energy bar, and a 3 - ounce energy drink. The weight carried by one runner is \(8 + 2.1+3\).

$$8 + 2.1+3=(8 + 3)+2.1=11 + 2.1 = 13.1$$

Step2: Let the number of runners be \(y\)

If there are \(y\) runners, then the total weight carried is the weight per runner times the number of runners. The expression is \(13.1y\)

Answer:

The expression is \(13.1y\), which means that the total weight carried by \(y\) runners is \(13.1\) ounces per runner times the number of runners \(y\)
