Suppose that you have $10 comma 00010,000 in a rather risky investment recommended by your financial advisor. during the first year, your investment decreases by 5050% of its original value. during the second year, your investment at the end of year one increases by 6060%. your advisor tells you that there must have been a 1010% overall increase of your original $10 comma 00010,000 investment. is your financial advisor using percentages properly? if not, what is your actual percent gain or loss of your original $10 comma 00010,000 investment?

20% loss

Explanation:

At time 0, original investment sum = $10,000

In year 1, loss was 50%.

= $10,000 * (1 - 50%) = 10,000 * 50% = $5,000

In year 2, gain was 60%.

= $5,000 * (1 + 60%) = 5,000 * 1.6 = $8,000.

Therefore, percentage change on original investment

= 8,000/10,000 - 1 = 80% - 1 = -20%.

Thus, percentage loss on original investment = 20%.

a recipe serves 8 people, and calls for 5 lbs of apples and 2 cups of flour. you want to prepare it for 24 people. divide 24 by 8 to get 3, and then multiply your ingredients by 3.

so for 24 people, you'll need 15 lbs of apples, and 6 cups of flour.
