The image contains two math problems (numbered 40 and 41) focused on problem solving.

Problem 40:

It reads: "Five groups of people enter the line for a ride at an amusement park. Each group of people enters either alone or in pairs. The expression $5 + 0.5j = 30$ models this situation. How many people are in the line?"

Let's solve this:

Given the equation: $5 + 0.5j = 30$

• "5" represents the five groups entering alone.
• "0.5j" represents the half of $j$, the people entering in pairs.
• "30" is the total number of people.

We need to find $j$, the number of people entering in pairs.

Problem 41:

It reads: "Use the formula to find a museum's volume V, where the width is 18 feet and the length is twice that. What is the area of the floor if the formula is used?"

This is asking to apply the formula for the volume of the museum and calculate the area of the floor based on the given dimensions.

Would you like me to solve both problems in detail?
