Question

The formula I = prt gives the simple interest / earned on an account where an amount p is deposited at an interest rate r for a certain number of years t. Use the table to order the accounts from least to greatest interest earned after 5 years.

And the table is Account: A p ($) 350 r (%) 4
B p ($) 500 r (%) 3.5
C p ($) 280 r (%) 4.25 Yes this is somehow an elementary question

Answer 1

With this kind of problem you can just put it in your calculator like this
`350*.04*5` and do that for every single one. And the way to turn a percent into a decimal is to move it over two places to the left. so 10% becomes .1 and 43% becomes .43 and so on.

The answer is:
Least is C which equals 59.5
The middle is A which equals 70
The most is B which equals 87.5

Hope I helped!
