Answer 2

Answer:

let the cost of the eraser be x and the pencil be x + .25

according to the question

8( x + .25 ) + 10x = 12.80

8x + 2 + 10x = 12.80

8x + 10x + 2 = 12.80

18x + 2 = 12.80

18x = 12.80 - 2

18x = 10.80

x = .60

so, the cost of the eraser is x = .60 cents

the cost of the pencil is x + .25 = .60 + .25 = .85 cents
