at a summer camp with 1,800 participants , 1 / 2 of the campers are aged 8 to 12 . next year , the number of campers aged 8 to 12 will increase by 1 / 3 . after this change , what percentage of the total 1,800 campers will the 8 - to 12 - year - olds represent ?
total - 1,800 participants campers are aged 8 to 12 = ( 1 / 2 ) * 1800 = 900 next year , campers are aged 8 to 12 = ( 4 / 3 ) * 900 = 1200 percentage = ( 1200 / 1800 ) * 100 = 66 2 / 3 % answer : option c
add(multiply(multiply(divide(multiply(divide(add(const_1000, multiply(8, const_100)), const_2), add(divide(const_1, const_3), const_1)), add(const_1000, multiply(8, const_100))), const_100), const_3), divide(multiply(multiply(divide(multiply(divide(add(const_1000, multiply(8, const_100)), const_2), add(divide(const_1, const_3), const_1)), add(const_1000, multiply(8, const_100))), const_100), const_3), const_10))
