Final answer:
The percent decrease in the price of the cooler from July to August is calculated by subtracting the new price from the original, dividing by the original price, and multiplying by 100. The decrease is 37.5%.
Step-by-step explanation:
The question asks about the percent decrease in the price of a cooler from July to August.
To calculate the percent decrease, you subtract the new price from the original price, then divide that number by the original price, and finally multiply the result by 100 to get a percentage. In this instance, Jack bought the cooler for $32 in July and Jill found it for $20 in August.
The calculation would be: ((32 - 20) / 32) x 100, which equals (12 / 32) x 100, and then 0.375 x 100, which gives us a 37.5% decrease. So, the cooler's price decreased by 37.5% from July to August.
