u^2-7u+12=0

(u-3)(u-4)=0

u=3,4

x^2=3,4

x^2=3                                    

x = ±√3

x^2 = 4

x=±2

The ratio of John's money to Jimmy's money is 5:8. Jimmy spent 1/4
erma4kov [3.2K]

Answer:

a. $3600

b. 6:5

Step-by-step explanation:

Put the question into an equation:

8x - 1/4 x 8x = 5x + 450

(simplify before solving) 6x = 5x + 450

(solve) 6x-5x = 450

x = 450

This means that Jimmy had 8 x 450 $ to start with = 3600

you can check this by subtracting a quarter of 3600 from 3600 and also multiplying 450 by 5 and then obtaining their difference. You get 450!

Now ratio of new amounts:

Jimmy now has: $2700

John still has: $2250

so ratio is 2700:2250

simplify to 6:5

Hope this helps
