Ok so what we need to find is 3 years of the simple interest so let’s get to it!
Ok so we found the principal price which is 250.00
And our rate is going to be 2.85%
A=P(1+rt)
Therefore the answer is going to be A=$271.38, therefore from the simple interest on a principal of $250.00 at a rate of 2.85% per year for 3 years is $271.38.
We need to leave m alone on the right hand side, so let's move everything else to the left hand side.
First of all, we can subtract b from both sides to get

Now, we can divide both sides by c to get

And so we solved the expression for m, because we have written an expression in the form
, where the right hand side doesn't depend on m.
It is 8 because you would do 9x8=72
The ratio...i think they answer is idk
Daniel was 10 three years ago, and Ben was 30. Now, Ben is 33.
