To find the answer you will write and equation in terms of the cost of a bag of chips.
3(cost of milk) + 4 (cost of water) + 8 (cost of bag of chips) = $21.30
3 (2c +1.60) + 4 (2c) + 8 (c) = $21.30 ; Simplify
6c + 4.80 + 8c + 8c = 21.30
22c + 4.80 = 21.30
- 4.80 -4.80
<u>22c </u> = <u>$16.50</u>
22 22
c = 0.75
The chips cost $0.75 each.
The milk costs (2 x $0.75 + $1.60) $3.10 each.
The water costs (2 x $0.75) $1.50 each.
The value 8 is significantly different from the other four values. Thus, the median would be the most appropr. measure of the center of this data distribution. Rearranging the data in ascending order:
8, 29, 31, 32, 33
The median is the middle value; it is 31.

Hey there :)

Change mixed fraction into an improper fraction


: are both even numbers, so you can further simplify by dividing by 2

To add fractions, we need same denominator to proceed. Here we have no problem since both denominators are 5


As a mixed fraction:

______________________________________________________

Let us change the mixed fraction into an improper fraction:


: You can further simplify this since both are divisible by 2

We have the same denominator set for subtraction, so you do not have to find common denominators
