Find the simple interest earned to the nearest cent, for the principal, interest rate, and time. $840,3%, 1 year

$865.20

Step-by-step explanation:

Use the equation: A = P(1 + rt)

A = 840(1 + (0.03 × 1)) = 865.2

A = $865.20

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
