To figure out what percent of the original price Jack paid, we must first divide the amount that Jack paid ($186.75) by the original price ($249).
186.75/249 = 0.75
Next, we must multiply this decimal value by 100 to convert it to its equivalent percentage. This is the same as moving the decimal point two places to the right, which also gives you the percentage equivalent.
0.75 * 100 = 75
Therefore, the correct answer is 75%.
Hope this helps!
