If a bottle and a stopper cost $1.10. How much does the stopper cost.
It could be anything. Maybe it was free with the bottle. More information is needed.
Perhaps you are thinking of this oldie.
A bottle and a cork together cost $1.00. The bottle cost 90 cents more than the cork. How much does the cork cost?
Bottle - 95 cents
Cork - 5 cents
ok. but how would you write an equation for that?
To calculate the cost of the stopper, let's assume the cost of the stopper is represented by 'x' (in dollars).
The given information states that the bottle and the stopper together cost $1.10. We can represent this as an equation:
Bottle + Stopper = $1.10
Since the cost of the stopper is 'x' dollars, we can substitute 'x' into the equation and solve for 'x':
Bottle + x = $1.10
Since the cost of the bottle is not given, we cannot determine its value directly. However, we know that the combined cost of the bottle and the stopper is $1.10.
Let's assume the cost of the bottle is represented by 'y' (in dollars). In that case, we can modify the equation as follows:
y + x = $1.10
Now, we need to consider that the sum of the costs of the bottle and the stopper is $1.10. So, we have:
x + y = $1.10
Since we are trying to determine the cost of the stopper ('x'), we'll re-arrange the equation to solve for 'x':
x = $1.10 - y
Now, we can see that the cost of the stopper ('x') is equal to $1.10 minus the cost of the bottle ('y').
Therefore, without knowing the specific cost of the bottle, we cannot determine the exact cost of the stopper.
