The cost of manufacturing a certain type of headphone varies inversely as the number of headphones increases. If 8000 headphones can be manufactured for $8.00 each, find the cost to manufacture 2000 headphones.

b is the answer that makes most sense

step-by-step explanation:

answer: 4 (:

step-by-step explanation:

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

160 cm

step-by-step explanation:

you have to add all the sides together
