Giving the following information:

Juan has a monthly budget of $100 to spend on entertainment. A concert ticket costs $20 while a movie ticket costs $10. This month Juan has attended one concert and 5 movies so far.

First, we need to determine the cost formula:

Total cost = 20*x + 10*y

x = number of concerts

y = number of movies

Now, we need to calculate the expense so far:

Cost = 20*1 + 10*5 = 70

Number of movies remaining = 30/10 = 3 movies
