Answer:
Total =790
40% kids=316
Step-by-step explanation:
Suppose x is the total number of people in concert
and it is given that 60% are adults so 40% left are kids
so 60% of x = 474
60/100 of x=474
x=(474*100)/60
x=4740/6
x=790
so total people in concert are 790 in number
so 40% of 790=# of kids
(40/100)*790=# of kids
79*4=316
so 316 equals 40% of kids in concert
Checking:
316+474=790
