Hi
We know that Area= length * width right?
So this is what we do.
Total area/length
25/54 / 5/9
You get the width to be 5/6
CHECK:
5/6*5/9=25/54
Hope this helps :)
Answer: Ok so first 0.05(6000 - x) + 0.07x = 372
300 - 0.05x + 0.07x = 372
300 + 0.02x = 372
0.02x = 72
x = 3600
He invested $3600 at 7% and $2400 at 5%.
