Madi bought 11 ft of ribbon for $1.32 per yard. how much did she pay for the ribbon?

First you need to figure out how many yards of ribbon you are buying. To do that divide 11 by 3. That equals 3 2/3 yards. You divided it by 3 because there are 3 feet in 1 yard.

next you need to change 3 2/3 yards into an improper fraction. Multiply the  whole number 3 by the denominator that ='s 9 and it to the numerator that ='s 11 so now you have the improper fraction 11/3 that represents the number of yards of ribbon you are buying.   Then multiply $1.32 * 11/3 = $14.52/3  reduced = $4.84

Paid $4.84 for the ribbon 

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

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
