Please help me figure out this math problem
If you had a total of 3404. And you wanted to split this up into two parts, and one part was 9% higher than the other, how do you figure that out?

I didn't get into college based on my math SAT score!

2. here you go
let x = smaller of the 2 desired numbers

x + (x * 1.09) = 3404

or

2.09x = 3404

devide both sides by 2.09

x = 3404/2.09 = 1628.7 (rounded to the nearest tenth.

and x*1.09 = 1775.3

check 1628.7 + 1775.3 + 3404

4. Thanks, tho I'm confused
why do you multiply by 1.09

What I did was - I started with 50 percent each. If one was 9 percent more, I added 4.5 to one and subtracted 4.5 from the other

So I had

54.5
45.5

So I did 3404 x .545 and got 1855 -
And 3404 x .455 and got 1549

Those numbers are different from yours.

:shrug:

5. Crabby Appleton's method is "higher, by 9% of the lower number"
yours is "higher, by 9% of the total score". The wording of the original problem should show which is more appropriate.
