Write an equation that shows how the total cost, y, depends on the number of sets bought, x.
Understand the Problem
The question is asking to formulate an equation that relates the total cost y to the number of sets bought x, considering each set costs $6. The equation will express this relationship mathematically.
Answer
$$ y = 6x $$
Answer for screen readers
$$ y = 6x $$
Steps to Solve
-
Identify the Variables
We need to identify what $x$ and $y$ represent. Here, $x$ is the number of sets bought, and $y$ is the total cost. -
Determine Cost per Set
The cost for each set is given as $6. This information will help us create the equation. -
Formulate the Equation
Since the total cost $y$ depends on the number of sets $x$, we can express this relationship mathematically as: $$ y = 6x $$ -
Write Final Equation
The equation $y = 6x$ represents that for every set bought, the total cost increases by $6.
$$ y = 6x $$
More Information
This equation shows a direct relationship between the total cost and the number of sets purchased, with $6 being the cost per set. It illustrates a linear function where the slope is $6$.
