What is Estimation cost?Estimation cost is the process of predicting how much a project or task will cost. It is used to help make decisions about the feasibility of the project and to plan for its budget. Estimation cost is based on past experiences, the current market and expected future conditions. The accuracy of an estimate can be improved by gathering detailed information about the project and its components. This information can include the cost of materials, labor and time needed to complete the project. Estimation cost is an important part of project management and is used in combination with other project management tools and methods such as scheduling, budgeting and risk management.

Carter and his children went into a movie theater and he bought $33 worth of drinks and candies. Each drink costs $4.50 and each candy costs $3. He bought 3 times as many drinks as candies. Determine the number of drinks and the number of candies that Carter bought.
Answers
The number of drinks and the number of candies that Carter bought are 6 and 2 respectively.
How to determine the number of drinks and candies?In order to determine the number of drinks and the number of candies that Carter bought, we would have to write a system of linear equation and assign variables to the number of drinks and number of candies respectively, and then translate the word problem into algebraic equation as follows:
Let the x indicate the number of drinks.Let the y indicate the number of candies.Since each drink costs $4.50 and each candy costs $3 and Carter bought 3 times as many drinks as candies;
x = 3y .......equation 1.
4.50x + 3y = 33 .......equation 2.
Substituting equation 1 into equation 2, we have:
4.50(3y) + 3y = 33
13.50y + 3y = 33
16.50y = 33
y = 33/16.50
y = 2 candies.
For the value of x, we have:
x = 3(2)
x = 6 drinks.

rise: -1
run: 3
Therefore, the slope of the line is -1/3. This is what x is multiplied by.
