Explanation Given: The following situation can be modified by linear functions. In each case, write an equation for the linear function and use it to answer the given question. Be sure you clearly identify the independent and dependent variables. Then briefly discuss whether a linear model is reasonable for the situation described. “The cost of leasing a car is $ 1000 for a down payment and processing fee plus $ 360 per month. For how many months can you lease a car with $ 3680 ?” The given description is a linear model as it can be represented in the form y = m x + b as y = 360 x + 1000 where x represent the time (number of months) which is the independent variable, y represents amount present with us (in dollars) which is dependent variable, m represents the slope (monthly payment to be paid) which equals $ 360 per month and the y − intercept represents the cost of leasing a car which is paid one-time and initially which is equal to $ 1 , 000. Formula used: Slope-Intercept form of a line equation: y = m x + b Description y = m x + b Step 1: Find the number of months to be leased, by substituting y = 3680 in y

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 …

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 experime…
