Answer:
The answer to your question is A.
<h3>The minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000</h3>
<em><u>Solution:</u></em>
<em><u>The expression to Michael earnings is:</u></em>

Where,
b is the base salary, which is $ 900 in this sum
c is the commission rate
Given that commission rate is 5%
s is the sales
Michael must have to earn at least $2500 in a month
Here, at least means, "greater than or equal to" 2500
The inequality is framed as:
base salary + 5 % on sales
2500

Solve the inequality

Thus, minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000
hello
from the question given, the dog walker charges a flat rate of $6 and an extra $30 per hour.
we can write out an equation in function notation
let the number of hours be represented by x

now we can proceed to solve the cost of the walk for 45 minutes

now we can input the value into the equation and know the cost for 45 minutes walk

from the calculation above, the cost of 45 minutes walk will cost $28.5
Answer:
([-3], [0]), ([3], [0])
Step-by-step explanation:
The given equation of the hyperbola is presented as follows;

The vertices of an hyperbola (of the form)
are (± a, 0)
The given hyperbola can we presented in a similar form as follows;

Therefore, by comparison, the vertices of the parabola are (± 3, 0), which gives;
The vertices of the parabola are ([-3], [0]), ([3], [0]).
