- Number opposed to building the skateboard ramps=44
- Total = 50
Percentage of those in favor = 
(b)In the age group 18-37

Percentage of those opposed to it = 
(c)
- Total Number of those in favor of building the skateboard ramps=73
- Total Number opposed to building the skateboard ramps=77
- Total = 150
Percentage of those in favour = 
What you do first is add 4 to both sides of the equation to get x alone and you get x=11. X is equal to 11.
8% of 20 is 1.6
This is because you take the percentage and divide it by 100 so that you have a decimal, then multiply that by twenty. So, 8% ÷ 100 = 0.08 then 0.08 × 20 = 1.6
Hope this helps!
