Hi Angel,
 
Here's an easy way to figure out this and any percentage question.  One per cent (1 dollar out of $100) of $800 would be $8.  So, if the man received 7 per cent out of $800, then just multiply $8 times 7, which is 56...so $56!  This is also an easy way to figure out how much tip to leave at a restaurant.  Glad to help!

What if the percent was 7.9%, the principal was $835.88, and the time was 3 1/2 years ? The student should know the formula and how to use it.
