Laura buys 3 packs of inventions.
20-11=9
(amount given-change=actual cost)
9 ÷ 3 = 3
(actual cost ÷ dollars per pack= number of packs bought)
Whatever the person above said lol
Resolve to do so
5x3=15
5x9=45
3+9=12
15+45=5x12
15+45=60
5x12=60
60=60
Which property is shown I did not understand but I think with the result 60 = 60 alone, but you will understand if you can not send me a comment, so I'll try to make you understand =)
