Johnny's dad brought him to watch some horse racing and his dad bet money. On the first race, he lost $5. On the second race, he won $1 more than twice the amount he previously lost. On the third race, he lost 1.5 times as much as he won in the second race. How much did he lose on average that day?

How much did he lose on the third race? ** On the third race he lost $15 because 10 x 1.5 = <<10*1.5=15>>15
How much did he lose on the first and third races? ** He lost a total of $20 on the first and third races because 15 + 5 = <<15+5=20>>20
