Question

Jon invests $4,100 into an account that pays 5 percent simple interest each year. What is the total balance in the account after 3 years

Answer 1

5% of $4,100 is $205 times 3 is $615 plus $4,100 is $4,715

Answer 2

5% simple interest each year what mean ?
so that 5% of 4100 get in plus for every year

than you know the rule of 3 simple so you can calcule easy this 5% sum of 4100 write in this way

4100 mean 100%
x mean 5% and now cross multiplie and calcule the x value

x = 5*4100 / 100 = ?

so after you get this x value so just multiplie it by 3 and will get so easy in this way the interest sum, for 3 years

in the last step this interest sum of 3 years you need assuming / adding to this invested sum of 4100 and in this way will get the correct answer so the total balance in the account after 3 years

hope helped easy understandably
