Step-by-step explanation:

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
