Catherine is using a spool of yarn to knit some items. She uses 14 yards of yarn to knit a scarf. The 3 8 number of yards of yarn she uses to knit a hat is 3 yards less than she uses to knit a scarf. How many 1 4 total yards of yarn does Catherine use to knit a scarf and a hat?

16.80 times .20= 3.36

step-by-step explanation:

c-   36

taxicab circle radius 9 has 4(9) = 36 points

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
