A phone company offers two monthly plans. Plan A costs $8 plus an additional $0.09 for each minute of calls. plan B cost $16 plus an additional $0.07 for each minute of calls.

a. For what amount of calling do the two plans cost the same? minutes

b. What is the cost when the two plans cost the same? $​

Answers

Answer: 72

Plan A = 30 +0.15x

Plan B = 16 +0.20x

30+0.15x = 16+0.20x

subtract 16 from each side

14 +0.15x = 0.20x

subtract 0.15x from each side

14=0.05x

x = 14/0.05 = 280 minutes

280*0.15 = 42 +30 = $72

280 * 0.20 = 56 +16 = 72

280 minutes and cost $72 each

what is 3/4b>15 solution

Answers

The solution set of the given inequality is  {b| b > 20}.

How to solve the inequality?

Here we have the inequality (3/4)b > 15 and we want to solve it. To do so, we just need to isolate the variable b.

And to do it, we can work with this like we would do with any equation, we can just multipy both sides by (4/3) so we get:

(4/3)*(3/4)*b > 15*(4/3)

b > 20

Then the solution set can be written as {b| b > 20}

That is the set of all values larger than 20.

Lisa's weekly pay increases from $525 to $546
Calculate her percentage pay increase.

Answers

546 - 525 = 21

21 is 4% of 525.


Lisa gained a 4% pay increase.

The percentage pay increase of Lisa's weekly will be 4%.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Lisa's weekly pay increased from $525 to $546. Then the percentage pay increase will be given as,

P = [(546 - 525) / 525] x 100

Simplify the expression, then we have

P = [(546 - 525) / 525] x 100

P = (21 / 525) x 100

P = 0.04 x 100

P = 4%

The percentage pay increase of Lisa's weekly will be 4%.

Find the slope ......

Answers

The slope for this problem is -4/3.

Step-by-step explanation:

To find the slope, we can look at it as Rise/Run. The rise is how many units up (+) a point is or how many units down (-) a point is from the starting point. The rise is how many units to the left or right a point is from the starting point.

Now that we understand Rise/Run, we can find the slope. If we go from the highest point, or the point farthest to the left in the picture shown, we can see that we need to go four units down to get to the same level as the next point, so we would be moving -4 units away from the point. We can also see the second point is 3 units to left.

With this information, we can now figure out that the slope is -4/3.

Don't hesitate to ask any questions.
