Jeremy Buys the New York Times from a new stand for $2.50 a day (skipping Sundays) and spends $30 per week on gasoline for his car (assume there are 52 weeks in a year) what is the total cost per year of the following pairs of expenses

answer: $2340

Step-by-step explanation:

2.50(6*52) + 30(52) = 780 + 1560 = 2340

(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.
