Answer:
Kyle drank 1.8 quarts of the jug.
Step-by-step explanation:
The quantity that Kyle drank from the jug is to equivalent to the product of the volume of the jug and portion that Kyle used. That is:
Where:
- Volume that Kyle drank, measured in quarts.
- Volume of the jug, measured in quarts.
If 
, the volume drank by Kyle is:
Kyle drank 1.8 quarts of the jug.

Answer:
Consider f: N → N defined by f(0)=0 and f(n)=n-1 for all n>0.
Step-by-step explanation:
First we will prove that f is surjective. Let y∈N be any natural number. Define x as the number x=y+1. Then x∈N, and f(x)=x-1=(y+1)-1=y. We conclude that f is surjective.
However, f is not injective. Take x1=0 and x2=1. Then x1≠x2 but f(x1)=0 and f(x2)=x2-1=1-1=0. We have shown that there are two natural numbers x1,x2 such that x1≠x2 but f(x1)=f(x2), that is, f is not injective.
Note:
If 0∉N in your definition of natural numbers, the same reasoning works with the function f: N → N defined by f(1)=1 and f(n)=n-1 for all n>1. The only difference is that you consider x1=1, x2=2 for the injectivity.
