Question

Mrs. Rock is planning an ice-cream party for her class. She needs one cone for each of her 25 students and one cone for herself. There are 10 ice-cream cones in a box.

1. How many boxes of cones should she buy?

2. How many cones will be left over?

Solve and Show work * I tried working this but wasn't successful 

Answer 1

25 + 1 = 26 ice cream cones needed

26/10 = 2.6 boxes need

So, she would need 3 boxes

10(3) = 30 cones

30 - 26 = 4 cones left over
