The manager of a weekend flea market knows from pastexperience that if he charges x dollars for a rental space atthe flea market, then the number of spaces he can rent isgiven by the equation y= 200 - 4x .(a) Sketch a graph of this linear function. (Remember thatthe rental charge per space and the number of spacesrented can’t be negative quantities.)(b) What do the slope, the y-intercept, and the x-intercept ofthe graph represent?
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.
