Question

A 1,500-foot tree has grown at a constant rate each year. In the equation below, t is the age of the tree in years.

Answer 1

Answer:

"30 feet per year".

Step-by-step explanation:

The given equation is

$30t=1,500$

This expression can be described as "the three grew 30 feet per year", and has grown 1,500 feet until now.

So, according to this expression, the unit rate of growth is 30 feet per year, because that's what expresses the coefficient of the independent variable.

Also, we could find the number of years took to the tree to be 1,500 feet tall

$t=\frac{1500}{30}=50$

It took 50 years to be that tall.

Therefore, the unit rate in the equation is "30 feet per year".

Answer 2

The unit rate is:  t= 50 years 

To find t, divide 30 by 1500. Your answer ends up being 50. 

Hope this helps.
