They all can be split up to 6 groups because 12+18=30 so each group will have 5 kids in it.
Answer:
30%
Step-by-step explanation:
What is the percent decrease if the original price is $582 and it went down 30%
or decreased 30%
Check:
582 x 0.70 = 407.4
582-407.4=174.6
174.6/582= 0.3
so we have a table of values, with x,y coordinates, so let's use any two of those points to get the slope of the table and use the point-slope form to get its equation

The population 10 years later will have increased by 3,040, making the population 18,240.
Hope this helps.<span />
.73 x .05= .0365
.733333333 x .0000000555555555= .036555555555
i think this is correct hope this helps
