An investment decreases in value by 30% in the first year and decreases by 40% in the second year. What is the percent decrease in percentage in the investment after two years

58%

Step-by-step explanation:

Let's say you started with 100 dollars. Then, the next year, since it decreased by 30%, you would now have 100 - 30 = 70 dollars. Then, you decrease by 40%, so now it is 70 - 28 = 42 dollars. So, the total percent decrease is 100-42 = 58 percent.
