a 3 2/5 - pound bag of yarn costs $5.25. what is the unit rate? round to the nearest cent.

$0.20 per ounce.

$1.54 per pound.

Step-by-step explanation:

We have been given that An 18 1/2 fluid ounces bottle of water costs $3.79.

To find the unit rate, we will divide total cost by number of oz of water as:

Convert mixed fraction into improper fraction:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
