Which steps show how to use the distributive property to evaluate 7.82? O A. 7(82) = 7(80 + 2) = 7.80 + 2 = 560 + 2 = 562 B. 7482) = 7180 + 2) = 7.80+ 7.2 = 560 + 14 = 574 C. 7(82) = 780 + 2) 7.80 + 80.2 - 560 - 160 = 720 D. 7(82) = 7080 + 2) = 7.80 -7.2 - 560 14 = 546

(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.

the answer is -81 is the answer
