A dry cleaning service decided to raise the price of dry cleaning shirts from $4.00 to $5.00. The same percentage increase was applied to dry cleaning a jacket. The old cost of dry cleaning a jacket was $10.00. What is the new cost of dry cleaning a jacket?: *
There are two ways of doing this. One is to use ratios.
5/4 = x/10
The other is to figure the percentage of $4 that is the $1 increase. Multiple that by $10 and add it to the $10.
I hope this helps. Thanks for asking.
11.00
To find the new cost of dry cleaning a jacket, you will need to apply the same percentage increase that was applied to the price of dry cleaning shirts.
First, let's calculate the percentage increase in the price of dry cleaning a shirt:
Percentage increase = (New price - Old price) / Old price * 100
Percentage increase = ($5.00 - $4.00) / $4.00 * 100
Percentage increase = $1.00 / $4.00 * 100
Percentage increase = 25%
Now that we know the percentage increase, we can apply it to the old cost of dry cleaning a jacket:
Increase in cost = Percentage increase * Old cost of jacket
Increase in cost = 25% * $10.00
Increase in cost = $2.50
Finally, we can find the new cost of dry cleaning a jacket by adding the increase in cost to the old cost:
New cost = Old cost + Increase in cost
New cost = $10.00 + $2.50
New cost = $12.50
Therefore, the new cost of dry cleaning a jacket is $12.50.
