Let's break down the problem step-by-step.
1. Understanding the Problem:
- Kelly initially has 9 friends.
- Out of these 9 friends, 2 do not want to play laser tag.
- The cost for playing laser tag per person is [tex]$4.
2. Calculating the Number of Friends Playing:
- To find out how many friends are actually playing, we subtract the 2 friends who do not want to play from the total number of friends.
- Number of friends playing = \(9 - 2 = 7\).
3. Calculating the Total Cost:
- Each friend who plays costs $[/tex]4.
- The total cost is calculated by multiplying the number of friends playing by the cost per person.
- Total cost = [tex]\( 7 \times 4 = 28 \)[/tex].
4. Choosing the Correct Expression:
- We need an expression that represents this situation.
- The correct expression would subtract the two friends not playing from the total number of friends and then multiply by the cost per person.
- The correct expression is: [tex]\(4(9 - 2)\)[/tex].
Therefore, combining these steps, we get:
- The expression is [tex]\(4(9-2)\)[/tex].
- Kelly will spend [tex]$28.
So, the correct answer is:
D. The expression is \(4(9-2)\). Kelly will spend $[/tex]28.
