Michael earns $900 per month, plus 5% commission on all his sales over $750. what is the minimum amount of sales Michael must ha

Alina [70]

<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>

$b + (c \times s)$

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 $\geq$ 2500

$900 + \frac{5}{100} \times s \geq 2500\\\\\ 900 + 0.05s\geq 2500$

Solve the inequality

$0.05s\geq 2500-900\\\\0.05s \geq 1600\\\\Divide\ both\ sides\ by\ 0.05\\\\s\geq 32000$

Thus, minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000

Select the correct answer. Which expression is equivalent to this polynomial? 15x − 24 A. 5(3x − 8) B. 3(5x − 5) C. 3(5x − 24) D

Scilla [17]

15x-24

the answer is not B because 3*-5= -15, we need -24

the answer is not C because 3*-24= -72

the answer is not A because 5*8= 40

Answer :

D. 3(5x − 8)

(3)(5x)(3)(-8)

15x-24= 15x-24

Solve 8x+2y=13 and 4x+y=11 using substitution

Aleonysh [2.5K]

Answer:

No Solution

Step-by-step explanation:

8x+2y=13 4x+y=11 Subtract 4x on both sides to isolate y

y=-4x+11 <---- Substitute this equation into the

equation 8x+2y=13

8x+2(-4x+11)=13

8x-8x+22=13

22=13 (not true)

No Solution
