Levi has a job offer in which he will receive $800 per month plus a commission of 2% of the total price of the cars that he sells. At his current job, he receives $1200 per month plus a commission of 1.5% of his total sales. How much must he sell per month to make the new job a better deal than his current job? Define variables, write a system of equations, and solve.
Answer:
Levi must sell more than 80000 cars per month for the new job to be better than the current job.
Step-by-step explanation:
New Job;
He receives $800 per month plus a commission of 2% or 0.02 of the total price of the cars.
Now, let the total amount he receives in a month be "y" and let the amount of cars sold be x.
Thus;
y = 800 + 0.02x - - - -(eq1)
Current Job:
He receives $1200 per month plus a commission of 1.5% or 0.015 of his total sales.
Thus;
y = 1200 + 0.015x - - - (eq2)
Substituting 800 + 0.02x for y into eq(2) gives;
800 + 0.02x = 1200 + 0.015x
0.02x - 0.015x = 1200 - 800
0.005x = 400
x = 400/0.005
x = 80000
This means Levi must sell more than 80000 cars per month for the new job to be better than the current job.

Ecuación 2:
10x + 20y = 8000
ayudaaa
Answer:
y = 300
x = 200
Step-by-step explanation:
Esta pregunta parece incompleta, parece que acá tenemos un sistema de ecuaciones:
x + y = 500
10*x + 20*y = 8000
Estas ecuaciones tienen que resolverse en conjunto, y de acá sacaremos un par de puntos (x, y) que son solución para ambas ecuaciones.
El primer paso para resolver esto es aislar una variable en una de las ecuaciones, en este caso podemos aislar x en la primera ecuación y así obtener:
x = 500 - y.
Ahora podemos reemplazar eso en la segunda ecuación y obtener:
10*(500 - y) + 20*y = 8000.
Ahora resolvemos esto para y.
5000 - 10*y + 20*y = 8000
10*y = 8000 - 5000 = 3000
y = 3000/10 = 300.
Y sabíamos que:
x = 500 - y = 500 - 300 = 200
Entonces la solución es:
y = 300
x = 200
does anyone know how to use substitution for
x+y=21
2x-15=y
Answer:
Step-by-step explanation:
Replace x
x=-y+21
2(-y+21)-15=y
Then solve the rest

The center of a circle lies on the line y=6x+2 and is tangent to the X axis at (-2,0) what is the equation of the circle in standard form?
Answer:
(x+2)^2 + (y+10)^2 = 100
Step-by-step explanation:
y = 6x + 2
Z(-2,0)
x = -2
y = 6 x (-2) + 2
y = -12 + 2
y = -10
M(-2, -10)
r = 0 - (-10) = 10
(x + 2)^2 + (y + 10)^2 = 100
Answer:
(x + 2)^2 + (y + 10)^2 = 100

Is 1/2 bigger or less then 20%
Answer:
1/2 is BIGGER than 20%
Step-by-step explanation:
1/2 is the same as 50% and 50% is greater than 20%
(Percent is out of 100 so half of 100 is 50.)
Hope that helps and have a great day!
Answer:
Well if it is a sale taking place then 1/2 off is less than 20% off
However if the prices are being increased then 1/2 more is bigger than 20% more.

What is the y-intercept of the line 3x – 7y = 42?
Answer:
(0, -6)
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Write standard form
3x - 7y = 42
Step 2: Rewrite in slope-intercept form
Subtract 3x on both sides: -7y = 42 - 3xDivide both sides by -7: y = -6 + 3/7xRewrite: y = 3/7x - 6Step 3: Find y-intercept
b = -6

(0, -6)

9x + 9 - 11 = 12x + 4 -3
9x - 2 = 12x +1
-2 = 3x + 1
-3 = 3x
x = -1
