Marvin inherited $25,000 from his grandparents. He placed the money in three different accounts that earn 2%, 6.25%, and 8.5% annual simple interest. The amount of money placed in the account that earns 2% was half the amount of money placed in the account that earns 6.25% interest. If he earned $1729 in interest combined after one year, how much money did he place in each account? I NEED THIS IN 20 MINUTES

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

your answer is -9
