hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"

the answer is: a greater percentage chance of loss

high risk investments had the characteristic of higher percentage of great return accompanied with higher percentage chance of loss.

this type of investments usually only suitable for investors that have enough capital to survive in case one or more of their investments fail. examples of high-risk investments are stocks and currencies.
