The number of daily sales of a product was found to be given by S = 300xe−x^2 + 300. (it's supposed to be -x2 after e) x days after the start of an advertising campaign for this product. (Round your answers to one decimal place.) (a) Find the average daily sales during the first 40 days of the campaign—that is, from x = 0 to x = 40. (b) If no new advertising campaign is begun, what is the average number of sales per day for the next 40 days (from x = 40 to x = 80)?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

x days after the start of an advertising campaign for this product. (Round your answers to one decimal place.)
(b) If no new advertising campaign is begun, what is the average number of sales per day for the next 40 days (from x = 40 to x = 80)?
