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
How would you write an equation for this?
let the cost of the cork be x cents
then the cost of the bottle is x+90 cents
equation: x + x+90 = 100
C is the cost of cork.
90+C + C=100
Thank you sooooo much!!!
thank you!
To write an equation for this problem, let's denote the cost of the cork as "x". Since it is given that the bottle costs 90 cents more than the cork, we can represent the cost of the bottle as "x + 90".
Now, we are told that the bottle and the cork together cost $1.00. So, we can write the equation as:
x + (x + 90) = 100
Simplifying this equation gives:
2x + 90 = 100
Subtracting 90 from both sides of the equation:
2x = 10
Dividing both sides by 2:
x = 5
Therefore, the cork costs 5 cents.
