The movie theater sold 3.45 tickets to show. If 2/3 of the tickets sold were adult tickets. Which cost $13.95 each how much money did the theater make from the sale of children’s ticket if they cost 2/3 of the amount of adult tickets ?

The movie theater sold 3.45 tickets to show, and 2/3 of the tickets sold were adult tickets, so there were 2/3 * 3.45 = <<2/3*3.45=2.3>>2.3 adult tickets sold

Since 1 adult ticket is $13.95 the theater made 13.95 * 2.3 = $<<13.95*2.3=32.085>>32.085 from the sale of adult tickets
Children's tickets cost 2/3 of the amount of adult tickets, meaning 2/3 * 13.95 = $<<2/3*13.95=9.3>>9.3
3.45 - 2.3 = <<3.45-2.3=1.15>>1.15 children's tickets were sold
Thus the theater made 9.3 * 1.15 = $<<9.3*1.15=10.695>>10.695 from the sale of children's tickets.
From all the movies tickets sold the theater made 32.085 + 10.695 = $<<32.085+10.695=42.78>>42.78. Answer: \boxed{42.78}.
