Answer 2

Calculating the Total Number of Yachts in the Competition

To solve this problem, we can use algebra to find the total number of yachts that participated in the competition.

Let's denote: - the number of small yachts as x - the number of large yachts as y

We are given that there were 18 small yachts and the number of large yachts was 3 times less than the number of small yachts.

We can express this information in the form of an equation: x + y = 18 (total number of yachts) y = (1/3)x (number of large yachts in terms of small yachts)

Now, we can substitute the value of y from the second equation into the first equation to solve for x.

x + (1/3)x = 18 x + (1/3)x = 18 (4/3)x = 18 x = 18 * (3/4) x = 13.5

Since the number of yachts must be a whole number, we can conclude that there were 13 small yachts and 5 large yachts in the competition.

Answer

Therefore, the total number of yachts that participated in the competition was 18 small yachts + 5 large yachts = 23 yachts.
