Answer:
The ratio of George age to Carl's age is 1:12.
Step-by-step explanation:
Let the age of George be 'g'.
Let the age of Alex be 'a'.
Also Let the age of Carl be 'c'.
Given:
The sum of their ages is 68.
So equation can be framed as;

Also Given:
Alex is 12 years older than George.
So equation can be framed as;

Now Given:
Carl is three times older than Alex.

But 
So we get;

Now Substituting equation 2 and equation 3 in equation 1 we get;

Subtracting both side by 48 using subtraction property of equality we get;

Now Dividing both side by 5 using Division property of equality we get;

Hence George age 
Now Alex age 
Also Carl's age 
Now we need to find the ratio of George age to Carl's age.

Hence the ratio of George age to Carl's age is 1:12.

Answer: 7.2$
hope it helps :)
step-by-step explanation:
Cost of each box = 3$
Cost of 3 boxes without 20% coupon = 9$
With 20% off Coupon = 9 by 100 multiplied by 20
(the zero's cut with each other leaving)
= 9 by 10 multiplied by 2
(9 multiplied by 2 = 18)
= 18 by 10
(18 divided by 10 = 1.8)
= the 20% of 9$ is equal to 1.8
when subtracted with the total cost leaves 7.2$
Least to Greatest: -3.05 1/2, -.875 1/3, & .40
