thanx ms.sue haha my manager does not know how to do any of this! i asked him for help but he doesn't get it.. so thank you! oh and the answer is $39.10!
To determine the current value of the comic book, we need to follow these steps:
Step 1: Calculate the 15% increase in value of the comic book from two years ago.
If the comic book was worth $40 two years ago, a 15% increase would be calculated as follows:
15% of $40 = (15/100) * $40 = $6
Step 2: Calculate the new value of the comic book after the 15% increase.
Adding the increase to the initial value:
$40 + $6 = $46
Step 3: Calculate the 15% decrease in value of the comic book from the previous year.
To calculate the decrease, multiply the new value by 15%:
15% of $46 = (15/100) * $46 = $6.90
Step 4: Calculate the final value of the comic book after the 15% decrease.
Subtracting the decrease from the previous year's value:
$46 - $6.90 = $39.10
Therefore, the comic book is now worth $39.10 after gaining 15% in value last year and then losing 15% in value this year.
