Answer 1

To determine Mr. Brown's salary after 3, 4, and 5 years at the school, we can use the salary function provided:

\[ s = 1,500y + 40,000 \]

where \( s \) is the total salary and \( y \) is the number of years he has worked.

Calculating for each year:

1. For 3 years (y = 3): \[ s = 1,500(3) + 40,000 = 4,500 + 40,000 = 44,500 \]

2. For 4 years (y = 4): \[ s = 1,500(4) + 40,000 = 6,000 + 40,000 = 46,000 \]

3. For 5 years (y = 5): \[ s = 1,500(5) + 40,000 = 7,500 + 40,000 = 47,500 \]

So the salaries after 3, 4, and 5 years are:

• After 3 years: $44,500
• After 4 years: $46,000
• After 5 years: $47,500

Now, let's summarize the points representing the salaries at those years:

• (3, 44,500)
• (4, 46,000)
• (5, 47,500)

Based on the responses provided, the correct option is:

(3, 44,500), (4, 46,000), and (5, 47,500).
