Explanation / Answer

43-

Price of pizza =$20

Suppose number of hungry people = X

Per person sharing in price = y

Then :

Per person Sharing in price(y)= 20/number of hungry people (X)

So per person sharing price is inversely proportional to number of hungry People

(46)-

As we know pounds is proportionaly attach with the kilograms

Given that pound (y) = 455lb ; kilograms = 206

Y= kX

455= k206

K=455/206

K=2.2087

So function is y = 2.2087x

Where y = weight in pounds & X= weight in kilograms
