Total - 1,500 participants
campers are aged 8 to 12 = (1/2)*1500 = 750
Next year, campers are aged 8 to 12 = (4/3)*750 = 1000
Percentage = (1000/1500)*100 = 66 2/3%

Total participants at summer camp = 1500
Campers aged 8 to 12 = \(\frac{1}{2}\) of 1500 = \(\frac{1}{2}\) x 1500 = 750
Next year campers aged 8 to 12 will increase by \(\frac{1}{3}\) = \(\frac{1}{3}\) of 750 = \(\frac{1}{3}\) x 750 = 250 .
Total campers aged 8 to 12 next year = 750 + 250 = 1000
Percentage of campers aged 8 to 12 to total 1500 = \(\frac{1000}{1500}\) x 100 = 66\(\frac{2}{3}\)%
Answer E ...
