company A :
30,000 + 0.03(37499) = 31124.97...sales less then 37500
30,000 + 0.03(37501) = 31125.03....sales exceed 37500
30,000 + 0.03(249000) = 37470 ...sales less then 250000
30,000 + 0.03(251000) = 37530....sales exceed 250000
company B :
25,000 + 0.05(37499) = 26874.95...sales less then 37500
25,000 + 0.05(37501) = 26875.05...sales exceed 37500
25000 + 0.05(249000) = 37450...sales less then 250000
25,000 + 0.05(251000) = 37550...sales exceed 250000
so i believe your answer is option b,
company A pays better when sales are less then 250,000, but company B pays better when sales exceed 250,000 <==
Answer:
see the explanation
Step-by-step explanation:
<em><u>The question is </u></em>
Identify the domain and the range, using words and inequalities
Let
x -----> the number of kilowatt-hours (kWh) of electricity per month
y ----> the price per month
we know that
Part 1) For the value of x between 0 kWh and 400 kWh
The price is equal to
therefore
The domain is the interval ------> [0,400)
The domain is all real numbers greater than or equal to 0 kWh and less than 400 kWh
The range is ($30)
The range is equal to $30
Part 2) For the value of x equal to 400 kWh or more per month
The domain is the interval -----> [400, infinite)
The domain is all real numbers greater than or equal to 400 kWh
The price is
<em>Find the range</em>
For x=400 kWh
so
The range is the interval -----> [38.8, infinite)
2
to work it out just go output f (x) - input x so, 3 - 1 = 2 and double check this using your next equations 4 - 2 = 2
Answer in the attachment.
Answer:
George is 12, Mary Lou is 24 and Kate is 10.
Step-by-step explanation:
To find these, start by setting George's age as x. This means that we can model Mary Lou's age as 2x, since she is twice as old. We can also model Kate's age as x - 2 since she is two years younger. Now we can add these 3 together and set equal to 46
x + 2x + x - 2 = 46
4x - 2 = 46
4x = 48
x = 12
This means that George is 12.
Mary Lou = 2x
Mary Lou = 2(12)
Mary Lou = 24
Kate = x - 2
Kate = 12 - 2
Kate = 10
