Explanation: To find the percent decrease from the list price to the price Tom can afford, divide Tom’s cost by the original cost to find the percentage that Tom’s price is compared to the original price.
2500/3000 = 0.833333 0.83=83%
83% is the percent that Tom’s price takes of the list price, which is 100% of the price. We need the percent that was taken out of the 100% to get to 83% There is 17% missing from 83% to make it 100%, so our answer is 17%
