To make widgets, Buford rents a shop for $2950 a month and calculates the materials for each widget are $38. How many widgets can he make in a month for $12,000?
Answer: 238 widgets
Step-by-step explanation:
12000$ - 2950$ = 9050$
9050$/38$≈238 (widgets)
The required, Buford can make at most 238 widgets in a month for $12,000.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let's first calculate the total cost of making x widgets in a month.
The cost of materials for each widget is $38, so the total cost of materials for x widgets is 38x.
In addition to the cost of materials, Buford has to pay $2950 per month for rent. So the total cost of making x widgets in a month is,
C(x) = 2950 + 38x
We want to know how many widgets Buford can make in a month for $12,000. So we want to solve the equation,
C(x) = 12000
Substituting the expression for C(x), we get:
2950 + 38x = 12000
38x = 9050
x = 238.16
Buford cannot make a fraction of a widget, so he can make at most 238 widgets in a month for $12,000.

The graph of this function is a parabola which opens upward.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given the following function:
g(x) = (x + 4)(x − 9)
The graph of this function is a parabola which opens upward and whose x-intercepts are:
x + 4 = 0
x = -4
x - 9= 0
x = 9
On the other hand, the y-intercept will be:
g(x) = (x + 4)(x − 9)
g(x) = (0 + 4) (0 − 9)
g(x) = -36
Hence, the graph of this parabola is attached below.

How many different 7-digit positive integers exist? (Note that we don't allow "7-digit" integers that start with 0, such as 0123456; this is actually a 6-digit integer.)
There are 9,000,000 seven-digit positive integers.
Explanation:
For the first digit, we have 9 choices: 1, 2, 3, 4, 5, 6, 7, 8, 9.
For each remaining digit, we have 10 choices: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Each choice is independent of the others. So, the number of total 7-digit positive integers is the product of all the numbers of choices for each digit.

Since 0 cannot be put as the first digit, there are 9 choices for the first digit, and the next 6 digits have 10 choices. So, there are 9 × 10^6 = 9000,000 numbers.
