It costs $3.20 to purchase 8 yards of lace.

Question

GinnyAnswer · Answer

Define the variable: Let c be the cost per yard. 
 Set up the equation: 8 c = 3.20 . 
 Solve for c : c = 8 3.20 ​ = 0.40 . 
 State the final answer: The cost per yard of lace is $0.40 ​ . 
 
 Explanation 
 
 Understanding the Problem We are given that it costs $3.20 to purchase 8 yards of lace. Our goal is to find the cost per yard. 
 
 Setting up the Equation Let c be the cost per yard of lace. We can set up the equation:

8 c = 3.20 
 This equation represents the fact that 8 yards of lace cost $3.20 . 
 
 Solving for the Cost per Yard To solve for c , we divide both sides of the equation by 8: 
 
 c = 8 3.20 ​ 
 Performing the division, we find: 
 c = 0.40 
 
 Final Answer Therefore, the cost per yard of lace is $0.40 . 
 
 Examples 
 Imagine you are buying lace for a craft project. Knowing the cost per yard allows you to calculate how much it will cost to buy a specific amount of lace. For example, if you need 5 yards of lace, you can easily calculate the total cost by multiplying the cost per yard ( $0.40 ) by the number of yards needed (5), which gives you a total cost of $2.00 . This simple calculation helps you budget and plan your craft project effectively.

It costs $3.20 to purchase 8 yards of lace.
