**A bat and a ball cost one dollar and ten cents in total. The bat costs a dollar more than the ball. How much does the ball cost?**

**Answer:**

Let the ball cost = x cents . So the bat shall cost x cents + 1 dollar = x + 100 cents. Now it is given Cost of Bat + Ball costs 1 Dollar + 10 cents i.e. 100 cents + 10 cents = 110 cents .

So, x (cost of ball ) + ( x + 100 ) (cost of bat ) = 2x+100 = 110 (from above )

So, 2x = 10 . So x = 5 .

Hence Cost of Ball = 5 cents
