Solve for n: [tex]$15=0.5 n$[/tex]

Question

GinnyAnswer · Answer

Rewrite the equation: 15 = 2 1 ​ n . 
 Multiply both sides by 2: 2 × 15 = n . 
 Simplify: 30 = n . 
 The solution is 30 ​ . 
 
 Explanation 
 
 Understanding the Problem We are given the equation 15 = 0.5 n and our goal is to solve for n . This means we want to isolate n on one side of the equation. 
 
 Rewriting the Equation We can rewrite the equation as 15 = 2 1 ​ n . 
 
 Multiplying Both Sides by 2 To isolate n , we can multiply both sides of the equation by 2: 2 × 15 = 2 × 2 1 ​ n 
 
 Simplifying the Equation Simplifying both sides, we get: 30 = n 
 
 Final Answer Therefore, the solution is n = 30 .

Examples 
 Imagine you are buying concert tickets online. Each ticket costs $0.50 (50 cents). If your total bill is $15, you can use the equation 15 = 0.5 n to find out how many tickets ( n ) you purchased. Solving this equation tells you that you bought 30 tickets. This kind of problem helps in everyday budgeting and understanding costs.
