Question

Joan puts $400 into a bank account. Each year the account earns 7% simple interest. How much interest will be earned in four years ?

$60
$72
$84
$112

Answer 1

$60

400 ÷ 7 = 57. 1428571429

Since that's not an option we estimate it. The closest number is $60 so, there's your answer!

I hope this helps! sorry if it's wrong :(
