Maddie and Elli are selling tickets to the school play. They cost $3.50 each. They sold tickets for several hours over the weekend. If Maddie sold 5 tickets per hour and Elli sold 8 tickets every other hour, how many tickets would they need to sell to have sold exactly the same amount of tickets? (Show all work to get credit)

m∠a is 90°

m∠b is 40°

(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.
