Answer:
The pencil cost $0.05 and the pen cost $1.05.
Step-by-step explanation:
Let, the price of the pencil is $ .
Given that the pen costs a dollar more than the pencil,
So, the price of the pen=$+1.
Therefore, ++1=1.10
, 2+1=1.10
, 2=1.10–1
, 2=0.10
, =0.10/2
, =0.05
The pencil cost $0.05 and the pen cost $1.05.

Answer:
See the graph of the given inequality in the attachment as shown below:
Step-by-step explanation:
Given the inequality: 
To graph this inequality on the number line.
Remember: 
- If the symbol is 
 then you fill in the dot 
- If  the symbol is 
 then you do not fill in the dot. 
Since, in the given inequality the symbol is '>'
