40

To find out how much money Doug has left, we need to subtract the amount he spent from the amount he earned.

First, let's calculate how much Doug spent on the CD. We know that he spent 1/4 of his earnings, so we can find this by multiplying his earnings ($40) by 1/4:

1/4 * $40 = $10

So, Doug spent $10 on the CD.

Next, let's calculate how much Doug spent on the movie ticket. We know that he spent 1/5 of his earnings, so we can find this by multiplying his earnings ($40) by 1/5:

1/5 * $40 = $8

So, Doug spent $8 on the movie ticket.

Now, let's find out how much money Doug has left. We subtract the total amount Doug spent ($10 for the CD and $8 for the movie ticket) from his earnings:

$40 - $10 - $8 = $22

Therefore, Doug has $22 left.
