How Long is 84 months

The correct answer is: $7\text{ years}$

Explanation

84 months divided by 12 months per year equals 7 years exactly. If you want other units (days, weeks, hours), those are approximate because calendar months vary in length and leap years add extra days.

Steps:

  1. Convert months to years: $84 \div 12 = 7$.
  2. Approximate days using the average month length ($\approx30.436875\text{ days}$): $84 \times 30.436875 = 2556.6975\text{ days}$ (≈2557 days).
  3. Convert days to weeks and hours:
  • Weeks: $2556.6975 \div 7 = 365.2425\text{ weeks}$ (≈365.24 weeks)
  • Hours: $2556.6975 \times 24 = 61360.74\text{ hours}$ (≈61,361 hours)

Note: For a specific calendar range (e.g., Jan 15, 2019 to Jan 15, 2026) 84 calendar months will equal exactly 7 years, but the exact number of days depends on which months and leap years are included.

A game is said to be fair if the expected value (after considering the cost) is 0. This means that in the long run, both the player and the “house” would expect to win nothing. If the value is positive, the game is in your favor. If the value is negative, the game is not in your favor. At a carnival, you pay $1 to choose a card from a standard deck. If you choose a red card, you double your money, but if you pick a black card, you do not get any. (A standard deck of cards has 52 cards. 26 of the cards are red.)

Calculating tax incidence Suppose that the U.S. government decides to charge cola consumers a tax. Before the tax, 10,000 cases of cola were sold every week at a price of $5 per case. After the tax, 3,000 cases of cola are sold every week; consumers pay $8 per case (including the tax), and producers receive $3 per case. 1) The amount of the tax on a case of cola is $??? per case. 2) Of this amount, the burden that falls on consumers is $??? per case, and the burden that falls on producers is ???$ per case. 3) True or False: The effect of the tax on the quantity sold would have been the same as if the tax had been levied on producers.
