Question

A bat and a ball costs $1.10. The bat costs a dollar more than the ball. How much does the ball cost?

Answer 1

so a bat and a ball together cost $1.10, and the bat cost $1.00 more than the ball to you are going to take $1.00 from $1.10 and that is going to leave you with a remainder of $0.10 left for the ball so the ball cost you $0.10. 

Answer 2

For this, we will make an equation. The bat costs 1 dollar more than the ball. We will use x as the value of ball. The equation will be x + (x + 1) = 1.10

x + x + 1 = 1.10
2x + 1 = 1.10
- 1 ___ -1
2x = .10
÷2 ÷2
x = .05
The ball cost .05 and the bat cost 1.05
