1. what is the cost of 2 magazines at $2.99 and three packs of gum at $.79? 2. 9, 15, 15, 6, 10, 19, 14, 16 mean median mode range show ur work plz

1 you already know it’s 8.35

2. Mean=11.7 (add them all together and dived by how many numbers there are in this case 9)

median=14 (put all numbers in order from least to greatest and find the middle one) I.e (2,6,9,10,->14<-15,15,16,19)

mode=15 (the number that appears the most)

Range=14 (the distance between the highest and lowest number)

Hope I’ve been helpful (this took way to long to make)
