Answer:
Dan is 29. Cary is 36.
Step-by-step explanation:
Let Dan's age now be D.
Let Cary's age now be C.
"Cary is 7 years older than Dan."
C = D + 7
"In 7 years the sum of their ages will be 79. "
In 7 years, the ages of Dan and Cary will be D + 7 and C + 7, respectively.
D + 7 + C + 7 = 79
C + D + 14 = 79
C + D = 65
C = D + 7
The last two equations in bold above form a system of equations. Since the second equation is already solved for C, we use the substitution method.
D + 7 + D = 65
2D + 7 = 65
2D = 58
D = 29
C = D + 7
C = 29 + 7
C = 36
Answer: Dan is 29. Cary is 36.
So first you figure out what 25% of $40.00 is whitch would be $30.00. Then what i think you would do next is add 6% of the cost of the dress. 6% of $30.00 is $1.80. so $30.00 + $1.80 = $31.80 dollors for the dress.

Step-by-step explanation:
Answer: 
has the least value because it's further from 0. The biggest negative number is the least because that number is further from 0. The smallest negative number is the biggest because it's closest to 0.
<u>Example:</u>
Find the least value of the following numbers: -6,-2,-1,-4,-10,-3
The least value in this problem is -10 due to the fact it's further from 0. The greatest value is -1 because it's closest to 0.
Least to Greatest Order: -10,-6,-4,-3,-2,-1
Greatest to Least Order: -1,-2,-3,-4,-6,-10
