Which Description Can Be Written as the Expression ?
In mathematics, expressions are used to represent a value or a relationship between values. They can be simple or complex, and can be used to solve a wide range of problems. In this article, we will explore the expression and determine which description can be written as this expression.
The expression is a linear expression, which means it is a polynomial of degree one. It consists of two terms: and . The first term, , is a product of a constant, , and a variable, . The second term, , is a constant.
To understand which description can be written as the expression , we need to break down the expression into its individual components. The first term, , represents the number of times a certain value is multiplied by . The second term, , represents a constant value that is being subtracted from the first term.
Description A states: "Hasaan wants to know how much savings is left in his account if he withdraws fifteen dollars." This description can be written as the expression if we let represent the number of times Hasaan withdraws dollars from his account. In this case, the expression represents the amount of savings left in Hasaan's account after he withdraws dollars.
Description B states: "Hasaan wants to know how many fifteen-dollar tickets he has to sell to make forty dollars." This description can also be written as the expression if we let represent the number of tickets Hasaan sells. In this case, the expression represents the amount of money Hasaan makes from selling tickets, minus the cost of dollars per ticket.
In conclusion, both Description A and Description B can be written as the expression . The expression represents a linear relationship between the number of times a certain value is multiplied by and a constant value that is being subtracted. This expression can be used to solve a wide range of problems, including calculating savings and determining the number of tickets that need to be sold to make a certain amount of money.
The expression has many real-world applications. For example, it can be used to calculate the cost of a product that is sold in units of dollars, minus a certain cost per unit. It can also be used to determine the number of tickets that need to be sold to make a certain amount of money, minus the cost of each ticket.
Here are a few example problems that can be solved using the expression :
- If Hasaan withdraws dollars from his account, and he has dollars left, how much savings does he have left?
- If Hasaan sells tickets, and each ticket costs dollars, how much money does he make from selling tickets?
- If a product is sold in units of dollars, and each unit costs dollars to produce, how much profit does the company make from selling units?
To solve these example problems, we can use the expression . For example, if Hasaan withdraws dollars from his account, and he has dollars left, we can plug in into the expression to get:
This means that Hasaan has dollars left in his account.
If Hasaan sells tickets, and each ticket costs dollars, we can plug in into the expression to get:
This means that Hasaan makes dollars from selling ticket.
If a product is sold in units of dollars, and each unit costs dollars to produce, we can plug in into the expression to get:
This means that the company makes dollars in profit from selling unit.
