There are 15 people in the chorus. Each year, the number of people in the chorus increases by 12%. There are 30 people in the band. Each year, 2 new people join the band. Part A: Write functions to represent the number of people in the chorus and the number of people in the band throughout the years. (4 points) Part B: How many people are in the chorus after 9 years? How many people are in the band after the same number of years? (2 points) Part C: After approximately how many years is the number of people in the chorus and number of people in the band the same? Justify your answer mathematically. (4 points) (10 points)

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
