Question

Two new student clubs start at a school. Each club has a plan to increase membership.

Answer 1

Answer:

The correct option is;

N = 4·w + 12

N = $3 (2)^w$

Step-by-step explanation:

The given plan the clubs will use to increase membership are;

Club 1: The starting number of members in the club = 12

The number of additional members added each week = 4

Club 2: The starting number of members in the club = 3

The total number of members at the end of each week = Double the the initial total membership

Therefore, we have;

For club 1, N = 12 + 4×w = 4·w + 12

N = 4·w + 12

For club 2, at week w, N = 3 × 2 × 2 ×...× 2 = $3 \times 2^w$

The correct option is therefore, N = 4·w + 12, N = $3 (2)^w$
