Answer 1

To determine how much Diego and Jackson spend on lunch each day, we need to analyze the provided information.

**Diego's spending:**
The equation \( y = 3.95x \) indicates that Diego spends $3.95 for each day he eats lunch.

**Jackson's spending:**
We can find out how much Jackson spends each day by calculating the average from the provided data.
1. Over 3 days, Jackson spends $13.65.
\[
\text{Average per day} = \frac{13.65}{3} = 4.55
\]

2. Over 8 days, Jackson spends $36.40.
\[
\text{Average per day} = \frac{36.40}{8} = 4.55
\]

So Jackson spends an average of $4.55 on lunch each day.

Now we compare the daily spending:
- Diego: $3.95 per day
- Jackson: $4.55 per day

Comparing these two amounts, we see that:
- $3.95 (Diego) < $4.55 (Jackson)

Therefore, the true statement is:

**A. Jackson spends more money on lunch each day than Diego.**
