Answer:
$105
Step-by-step explanation:
$15 for one case of snicker bars. Since it's $30 for 2. He needs 140 so 140 divided by 20(which is in one case) = 7. So he needs 7 cases to have 140 snicker bars. Well, if each case itself is $15 and we need 7 cases. 7 times 15= 105. It's going to cost him $105 to fill that vending machine.
Answer:
true
Step-by-step explanation:
2 classes of 21 students each
21 × 2 classes = 42 students in total
42 × 3 mins = 126 minutes for 42 students
10 mins for 2 class pics = 20 minutes
126 + 20 = 146 minutes = 2 hours and 26 minutes
It should take 146 minutes (2 hours and 26 minutes) to take all the pictures.
