30% of 40 = 0.30(40) = 12......so 12 tables seat 4 people per table = 12 x 4 = 48 seats.......tables remaining seat 22 people (22 seats).
48 + 22 = 70 seats total

30% of 40 is
30/100 times 40=
3/10 times 40=
120/10=
12

12 seat 4 people

40-12=28 seating 22

total seats=
12*4+28*22=
48+616=
664

664 seats
