Suppose a retail seller of jeans currently has 40 customers. The retailer offers the following quantity [10] discount to these 40 customers. Buy the 1" pair of jeans at a price of $100, buy a 2d pair of jeans at a price of $80, buy a 3rd pair of jeans at a price of $60, and buy a 4th pair of jeans at a price of $40. Suppose the cost to the retailer for each pair of jeans is $40. Suppose of these 40 customers, all buy the 1" pair of jeans, 30 of these 40 buy a 2nd pair of jeans, 20 of these 30 (i.e., those who bought a 2nd pair) buy a 3rd pair, and 10 of the 20 (i.e., those who bought a 3rd pair) buy a 4th pair. The profit to the retailer from selling jeans to these 40 customers in this way equals:
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.
