The rate of change of stamp collection was $57.5 per year.
Rate is comparison of two related quantities.
Often the second quantity is time (per second, per hour, etc) but it can be anything.
Can be in the style "this per that" or as a single number calculated using division.
Example: Sam makes 3 pancakes every 6 minutes, that is a rate of:
• 3 pancakes per 6 minutes
• 0.5 pancakes per minute
• 30 pancakes per hour
• an hourly rate of 30
By formula the rate of change = Change in cost/ Time taken
=( $980 - $420)/ 8years
= $460/ 8 years
= $57.5 per year
Thus the rate of change of stamp collection was $57.5 per year.

Answer:
I'm pretty sure it's the 8 feet deep hole
Step-by-step explanation:
You're earning 8 dollars so that can't be negative.
Temperature can be negative but it doesn't have the - in front of it.
It would be a confusing question if that's the answer because then you'd be basically guessing at it.
I don't think it's the throw because you can't actually throw in negative/throw backwards for it to be negative.
8 feet hole is the only one that makes sense, since you're going down
74-50 is 24. 24/2 is 12.
your number was 12.
Okay so a dilation means that you would multiply the area by your scale factor. 103 times 3 is 309. Your answer is 309
