There are 128 teams in a softball tournament. In each round, half of the teams are eliminated. Which function can be used to find the number of teams remaining in the tournament after `x` rounds?

Answer 1

The number of teams remaining in the tournament after `x` rounds can be found using the function:

Number of teams remaining = 128 * (1/2)^x

Answer 2

The amount of fertilizer in a landscaping company's warehouse decreases at a rate of `2\%` per week. The amount of fertilizer in the warehouse was originally, `64,000` cubic yards. Which function models the amount of fertilizer in cubic yards left after `w` weeks?

Answer 3

The function that models the amount of fertilizer in cubic yards left after `w` weeks can be given by:

Amount of fertilizer left = 64,000 * (1 - 0.02)^w

where `(1 - 0.02)^w` represents the decrease in the amount of fertilizer per week.
