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.
![A manufacturer incurs the following costs in producing x water ski vests in one day, for 0<x< 175: fixed costs, $500; unit production cost, $25 per vest; equipment maintenance and repairs, 0.05x dollars. So, the cost of
manufacturing x vests in one given day is given by C(x) = 0.05x
+ 25x + 500, where 0<x< 175.
(A)
(B)
What is the average cost C(x) per vest if x vests are produced in one day?
Find the critical numbers of C(x), the intervals on which the average cost per vest is decreasing, the intervals on which the average cost per vest is increasing, and the local extrema.
