Answer:
Tenley has to deposited any amount from $50 and above.
Step-by-step explanation:
From the above question, we can deduce that if your bank balance is below 0, = - , you would be charged $30
Hence,
First she has to pay the bank charges of $30, and to prevent the outstanding charge of $19.95 for generating about charge she has to deposit any amount above $19.95
The amount she has to deposit is
$30 + (x > $19.95)
Assuming x is $20 and above
= $30 + $20 = $50
Hence, Tenley has to deposited any amount from $50 and above.
<u>Answer</u>:
18 clips for $7.38 is the best value deal.
<u>Step-by-step explanation:</u>
An office is restocking office supplies. The table below shows the cost for the number of boxes of paperclips. We need to find what is the best value is.
To find the best value for money we can check the price of each paperclip.
To check the price of each paper clip we can use the following formula:

Now we can calculate the best value deal as follows:





So, from looking at the prices of each paperclip we can conclude that the 18 clips for $7.38 is the best value deal.
You have to add 10 last.
divide 75÷8 and then add 10
You are given two x and y pairs: (100,45) and (570,162.5)
First solve for the slope, m.
m = (162.5 - 45) / (570 - 100)
m = 117.5 / 470
m = 0.25
Not only is "m" the slope but it is the rate (dollars per minute) in the question. So it's 25 cents per minute to use the phone.
After imputing "m" the linear equation looks like this:
y = 0.25x + b
Use either point as (x,y) to solve for the y-intercept "b". I'll use (100,45)
45 = 0.25(100) + b
45 = 25 + b
45 - 25 = b
20 = b
Not only is "b" the y-intercept but it is also always the flat fee added on to linearly increasing cost questions like this.
Final equation is:
y = 0.25x + 20
Part B.) If 939 minutes are used. Just put that in for x and solve for y.
y = 0.25(939) + 20
y = 234.75 + 20
y = 254.75
