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 plant food is made from three chemicals, labeled I, II, and III. In each batch of the plant food, the
amounts of chemicals II and III must be in the ratio of 4 to 3. The amount of nitrogen must be at least
60 kg. The percent of nitrogen in the three chemicals is 10%, 6%, and 2%, respectively. If the three
chemicals cost $1.06, $0.83, and $0.61 per kilogram, respectively, how much of each should be used
to minimize the cost of producing at least 700 kg of the plant food?
The minimum cost plant food is made with kg of chemical I, kg of chemical II, and
kg of
chemical III.
