Students observing a caterpillar crawl on a tree noticed that the caterpillar crawled upwards 3/8 of an inch every minute. The caterpillar was already 4.5 feet off the ground when the students began observing.

Which function represents the total number of inches the caterpillar crawls after x minutes?

1. f(x)=3/8x+4.5
2. f(x)=3/8x+54
3. f(x)=54x+3/8
4. f(x)=4.5x+3/8

4? Already tried 1 but was incorrect.

first off, how many inches in 4.5 feet?
That's the starting point.
it is option 2: f(x)=3/8x+54 for anyone looking this up later
