Write an equation for the following problem...
you spend $16 on 3 notebooks and x binders. Notebooks cost $2 each and binders cost $5 each. Write an equation you can use to find the number of binders you bought.
6 + 5x = 16
To write an equation, let's first determine the cost of the binders. We know that the cost of notebooks is $2 each and the cost of binders is $5 each. Since you spent a total of $16, the equation can be formed as follows:
Cost of notebooks + Cost of binders = Total cost
The cost of notebooks is $2 multiplied by the number of notebooks, which is 3. So, the cost of notebooks is 3 * $2 = $6.
Now, let the number of binders be represented by x.
The cost of binders is $5 multiplied by the number of binders, which is x. So, the cost of binders is x * $5 = $5x.
Using the equation, we can combine the cost of notebooks and binders to equal the total cost, which is $16:
$6 + $5x = $16
Now, this equation represents the given problem and can be used to find the number of binders you bought.
