Gloria operates three self-service gasoline stations in different parts of town. On a certain day, station A sold 600 liters of premium, 800 liters of super, 1000 liters of regular gasoline, and 700 liters of diesel fuel; station B sold 700 liters of premium, 600 liters of super, 1200 liters of regular gasoline, and 400 liters of diesel fuel; station C sold 900 liters of premium, 700 liters of super, 1400 liters of regular gasoline, and 800 liters of diesel fuel. Assume that the price of gasoline was Sh3.80/liters for premium, Sh3.60/liters for super, and Sh3.40/liters for regular and that diesel fuel sold for Sh3.70/liters. Use matrix algebra to find the total revenue at each station
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.
