Answer and Step-by-step explanation:
To calculate how much Halima's mom spent at the movies, we need to consider the cost of movie tickets and the cost of popcorn for each child.
Given that movie tickets are $13 per child and bags of popcorn are $7 each, we can calculate the total amount spent as follows:
1. Cost of movie tickets: Since Halima and her three friends are going to the movies, the cost of movie tickets for each child would be $13. So, the total cost of movie tickets would be $13 multiplied by 4 (number of children), which equals $52.
2. Cost of popcorn: Each child is also getting a bag of popcorn, which costs $7 per bag. Since there are four children, the total cost of popcorn would be $7 multiplied by 4, which equals $28.
3. Total cost: To find the total amount spent, we need to add the cost of movie tickets and the cost of popcorn. So, $52 (cost of movie tickets) plus $28 (cost of popcorn) equals $80.
Therefore, Halima's mom spent $80 in total for movie tickets and popcorn for Halima and her three friends.
