The answer is seventy percent. To find this, first find the amount of the discount, and then use a proportion to find the percent. Here’s the idea.
First, set up a proportion. To determine the amount of the discount, subtract the price paid from the original price.
Next, replace the words in the proportion with the known amounts. Then, cross multiply. Twenty-four dollars and fifty cents times one hundred equals percent of discount times thirty-five dollars.
Now, divide both sides of the equation by thirty-five dollars. And, we find that Joline’s skirt was sold at a seventy percent discount!
