Answer:

Ok so 8 pencils equals $6.80. So divide that up by 8, and you get $0.85. So next do $0.85 - $0.25 which you get $0.6. The answer is $0.60

Step-by-step explanation:

Cost of pencil = x+0.25

Cost of eraser =x

Cost of 8 pencil = 6.80

Cost of 1 pencil = 6.80/8 = 0.85

So the cost of eraser

0.85 =x+0.25( cost of 1 pencil)

0.85-0.25 = x

0.6 = x

So the cost of eraser is $ 0.6
