Answer:
Let p be the number of pencils.
3(14-p)=30+p
42-3p=30+p
4p=12, p=3.
So Peter ends up with 33 and Tony with 11. 3*11=33, so that confirms that Tony gave Peter 3 pencils.

Answer:
The correct option is <u>$2.50</u>.
Step-by-step explanation:
This can be determined by calculating the change in total cost of lunch using the data given in the question as follows:
Slice of pizza Total cost of lunch ($) Change in total cost of lunch ($)
0 7.5 -
1 10 2.5
2 12.5 2.5
3 15 2.5
4 17.5 2.5
5 20 2.5
6 22.5 2.5
7 25 2.5
8 27.5 2.5
Since the change in total cost of lunch in table abov is constant at $2.50, this implies that for each additional slice of pizza that is purchased, the total cost of lunch increases by $2.50.
Therefore, the correct option is <u>$2.50</u>.
True

1/4x + 5 = =4
subtract 5 to both sides
1/4x = 4 - 5
1/4x = -1
multiply 4 to both sides
x = -1 x 4
x = -4
