At a carnival, Amy bought
6
packs of
15
tickets each. She has used
38
of the tickets so far. How many tickets does she have left?
+1632 6 packs of 15 tickets each has the key word "of". Of means multiply, so 2 packs of 2 pokemon cards each is 2 x 2 = 4.
6 packs of 15 tickets each means 15 + 15 + 15 + 15 + 15 + 15 = 15 x 6 = 90 tickets in total. If she has used 38 already, use subtraction.
90 - 38 = 52. Amy has 52 tickets left.
