I'm doing IPRT which is percents and stuff, the questions says " Trevon invested in $1,500 in an account with an interest rate of 4.25% If he plans to retire in 18 1/2 years , how much total will be in his account ." i need to know 18 1/2 as a whole number i know how to do the rest.

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 : )
