To solve this problem you must apply the proccedure shown below:

1. She has a total of 50 DVDs of 90 minutes each one of them. The cost of each DVD was 11€.

2. Therefore, to calculate the total cost of the collection, you must multiply the cost of each DVD by the total number of them:


total=(11)(50)=550

3. To calculate the total minutes of the collection, you must multiply 90 minutes by the total number of DVDs:


(90min)(50)=4500min

Therefore, the answer is: 550€ and 4500 minutes.
