Step-by-step explanation:
Put them in order:
4.7
5.6
6.2
7.4
7.9
8.4
10.2
10.6
11.2
13.1
15.4
15.5
Find the middle number:
Since there are 12 numbers, you will have 2 middle numbers which will be the 6th and 7th number: 8.4 and 10.2
Add them together:
8.4 + 10.2 = 18.6
18.6/2 = 9.3
$16.25
9.75/3 = 3.25
So therefore 1 bag costs $3.25.
$3.25 × 5 = $16.25
-8
4(2+2(-2))
distribute : 8 + -16
add: -8
