6 billion= 6*10^9.

We have an equation: ?/ (6*10^9)= 20/100

Cross multiply:
100*?= 20* 6*10^9
⇒ ?= 20* 6*10^9/100= 1.2*10^9

About 1.2*10^9 people live on less than $1 per day~

PLEASE HELP I WILL GIVE EXTRA POINTS
Evgen [1.6K]

Answer:

  C

Step-by-step explanation:

A relation is a function if each input gives exactly one output. There is one price for each number of pounds, so the relation is a function.

__

<em>Additional comment</em>

Relations expressed in terms of ordered pairs or tables can be identified as "not a function" if any input (x) value is repeated. Relations expressed as a graph will be "not a function" if any vertical line intersects the graph at more than one point. (This is called "the vertical line test.")

The cost function in this case is a straight line through the origin. It has a slope of $5.99/lb. Any polynomial relation will be a function.
