When a buffet restaurant charges $12.00 per meal, the number of meals it sells per day is 400. For each $0.50 increase to the price per meal, the number of meals sold per day decreases by 10. What is the price per meal that results in the greatest sales, in dollars, from meals each day?

Discount is the term used to describe the sum or portion subtracted from an item's usual selling price — a good or service's price decreases when given a discount. For instance, if the item breaks, we can ask the manager for a discount.
When a bond's price is expected to be less than its face value, it is known as a discount. Discounts are a form of product cost price reduction or deduction. When customers receive discounts on various things, it is frequently employed in consumer transactions. How to Find Discount
1.) The rate is frequently stated as a percentage.
2.) To calculate the discount, we must multiply the rate by the starting cost.
3.) To calculate the sale price, we must subtract the discount from the purchase price.
¶ Rate of Discount = Discount% = Discount List / Price×100.

For the linear function, f, the table shows several values of x and their corresponding values of f(x). What is they-intercept of the graph of y = f(x) in the xy-plane?

The frequency table above shows the distribution of the actual number of fluid ounces of water in a random sample of 80 20-ounce bottles of the water at a bottling plant. Bottles are only sold if they contain at least 19.8 but no more than 20.2 fluid ounces of water. If the proportion of bottles that can be sold is the same for the sample and the 16,000 20-ounce bottles produced at the plant each day, how many of the 16,000 bottles cannot be sold?

A local restaurant gives teachers a 20% discount on all their meals. If a teacher pays $14.00 for a meal after the discount was applied, what was the price of the meal before the discount?
