A pencil and an eraser cost 1.10 together. if the pencil costs one dollar more than the eraser how much does the eraser cost

1 pencil + 1 eraser = $1.10

Pencil cost $1 more than the eraser.

⇒ If we take away $1 from the total, both the pencil and the eraser will cost the same.

⇒ $1.10 - $1.00 = $0.10

Divide by 2 to find the cost of the eraser.

⇒$0.10 : 2 = $0.05

Find the cost of the pencil, which is $1 more than the eraser.

⇒ $0.05 + $1 = $1.05

Answer: The eraser costs $0.05
