The cost of pencil is 25 cents more than the cost of a eraser. If the cost of 8 pencils and 10 erasers is $12.80, find the cost of each

P= E+.25
P E $
8 10 12.80
Solution:
P= 8 pieces
8*.25 = 2.00
12.80- 2.00 = 10.80
10 pieces+ 8 pieces = 18 pieces
10.80/ 18= 0.60
0.60+.25 = 0.85.
Answer:
Pencil= $0.85
Eraser=$0.60
