A bottle of wine costs $10. The wine is worth $9 more than the bottle. How much is the bottle worth?

Answer :

$10 - $9 = $1

Total - Wines price = Bottle's price

The ball costs $0.05.

The ball costs $0.05.

To find the solution, set up a system of equations. Let b represent the cost of the ball. The bat costs $1 more, so it would be b + $1. Together, they cost $1.10, which leads to the equation b + (b + $1) = $1.10.

  1. Step 1: Set up the equation: b + (b + $1) = $1.10.
  2. Step 2: Solve the equation: 2b + $1 = $1.10.
  3. Step 3: Subtract $1 from both sides: 2b = $0.10.
  4. Step 4: Divide by 2 to find the value of the ball: b = $0.05.
