i will appreciate anyone that can help me?
let x and y be the two amounts
x be the amount the gets you a 9% profit and y be the amount that gets you the 7% profit
so this means x+y = 2900 is your first equation
solve for y to get y = 2900 - x
since x dollars invested gives you a 9% profit, this means we go from x dollars to 1.09x dollars y dollars invested gives you a 7% profit, this means we go from y dollars to 1.07y dollars they add up to 1.09x + 1.07y
it's given that the "total profit was 233", so 1.09x + 1.07y = 233 Now plug in y = 2900 - x to get 1.09x + 1.07y = 233 1.09x + 1.07(2900 - x) = 233 and solve for x
oh wait...hmm i'm thinking of something else, the second equation should be 0.09x + 0.07y = 233 plug in y = 2900 - x to get 0.09x + 0.07(2900 - x) = 233
now solve 0.09x + 0.07(2900 - x) = 233 for x
u add 0.09 + 0.07 = 0.16 then u x 2900 =464 so 233x = 464?
i have to get the profit for 9% and also 7 % so I dont think I got it right?
0.09x + 0.07(2900 - x) = 233 0.09x + 0.07(2900) - 0.07x = 233 0.09x + 203 - 0.07x = 233 0.02x + 203 = 233 0.02x = 233 - 203 0.02x = 30 x = 30/0.02 x = 1500 So $1500 was invested and it generated a 9% profit
use this x value to find y
thank you I got it. thank you so much you helped me a lot. you should honestly be a tutor, to bad you dont live in Boise idaho I would pay you to tutor me.
I am a tutor lol, I could tutor online if you want
that's kinda what I just did right now
