In the first week, it completed 25% of the toys, in the second week, it completed 30% of the toys, and in the second week, it produced 450 more toys than in the first week. How many toys are there in total?

Suppose there are x toys in this batch, then:
x*30%-x*25%=450
The solution is: x = 9000
So there are 9000 toys in this batch
