The making of the candles is an illustration of unit rates
The minimum amount of wax the store owner needs to make 60 candles is 180 grams
<h3>How to determine the amount of wax needed</h3>
The number of candles is given as:
n = 60
The amount of wax needed for a candle is not given.
So, we make use of an assumed value.
Assume the minimum amount of wax needed to make a candle is 3 grams.
Then, the amount needed for 60 would be:
Amount = 60 * 3
This gives
Amount = 180
Hence, the minimum amount of wax the store owner needs to make 60 candles is 180 grams (using the assumed value)

Let the distance between the tree and the first point (point H) be x and let the height of the tree be h, then:
Also, the distance from the tree to the second point (point L) is x + 60, thus:
From (1) and (2), we have:
From (1):
h = x tan 40° = 132.4 (0.8391) = 111.1 feet.
Therefore, the height of the tree is 111.1 feet
