Question

At a restaurant you only have $30 to spend on dinner.In addition to the cost of the meal you must pay 8% sales tax and leave a 20% tip.What is the most expensive item you can order

Answer 1

The most expensive item you can get is $23.44

Explanation:

Because we are adding 8% in tax and 20% in tip, we know that overall we are spending 128% of the total dinner. So, we can divide the $30 we have to spend by 128% in order to find the original price of the item (don't forget to turn the percentage into a decimal first).

$30/1.28 = $23.44
