Answer: $2000 + 0.08s ≥ $2500
Step-by-step explanation:
The expression that will be used to calculate the earnings of Liz will be:
= b + (c × s)
Where:
b = base salary = $2,000
c = commission rate = 8% = 8/100 = 0.08
s = the sales that the commission rate will be applied against.
The inequality to find amounts of sales that will meet Liz goal will be:
= b + (c × s)
= $2000 + (0.08 × s) ≥ $2500
= $2000 + 0.08s ≥ $2500
When faced with an unknown variable in a maths problem, it is advised to find the subject formula and then use it to solve the equation to find the answer.
<h3>What is an Unknown Variable?</h3>
This refers to the type of variable in a given equation that has to be solved for because its properties or value is not known.
Hence, we can see that when faced with an unknown variable in a given math problem, it is better to find the subject formula, then input the value of this into an equation, to find the value of the variable.

Answer:
B and D
Step-by-step explanation:
The function is the relation between the sister's shoe size and her age, being age the independent variable x, and the shoe size the dependent variable y.
If we think this through, we'll find out that age is a discrete variable, and shoe size too. Discrete variable refers to those variable that only admit whole numbers, they don't admit decimal numbers. So, in this case, both variables aren't represented by decimal values. So, the relationship is discrete function, punctual data.
Similarly, the function must be restricted to positive integers, because, as we already said, the variable only admit discrete values and we have to add that only should admit positive discrete values, because age cannot be negative, it wouldn't make sense, also shoe size cannot be negative. In this context, negative numbers don't make any sense.
I think that's the element on the second row and the first column which is 15.
The area is twenty because five times four equals twenty
