Complete question :

You have recently begun reasearching phone billing plans. Phone company A charges a flat rate of $75 a month. A flat rate means that your bill will be $75 each month with no additional costs. The billing plan for Phone Company B is a linear function of the number of texts that you send that month. That is, the total cost of the bill changes each month depending on how many texts you send.

Input (no of text) __ cost of bill

50 ______________ $50

150 ______________$60

200 _____________ $65

500 _____________ $95

At what number of text will be phone plan be the same ; At what Number of text is company A the better choice ; At what number of text is company B the better choice.

Answer:

Cost is the same at, x = 300

at number of text, x < 300 phone plan B is better ;

at number of text, x > 300 phone plan A is better

Step-by-step explanation:

Let cost = y

Let x = Number of text

Company A :

y = 75

company B :

y = mx + c

m = slope = (y2 - y1) / (x2 - x1) = (95 - 50) / (500 - 50) = 45 / 450 = 1/10

When y = 50, x = 50

50 = 1/10(50) + c

50 = 5 + c

c = 50 - 5 = 45

Company B:

y = 1/10x + 45

When charge will be the same :

75 = 1/10x + 45

75 - 45 = 1/10x

30 = 1/10x

300 = x

Cost of phoe plan is the same at number of text = 300

At text = 299

Company B :

y = 1/10(299) + 45

y = 74.9

Hence, at number of text, x < 300 phone plan B is better

At text = 301

Company B :

y = 1/10(301) + 45

y = 75.1

Hence, at number of text, x > 300 phone plan A is better

Answer:

$45 after the discount

Step-by-step explanation:

Set up a proportion.

     \frac{x}{50} = \frac{10}{100}      $50 is the total amount and make the 10% a decimal

x(100) = 50(10)

100 = 500

100 ÷ 500

x = 5     <-- We have to subtract this amount from the total

$50 - $5 = $45 <-- total after the discount

<u>Hope this helps!!</u>

Maureen spends four times as long riding the train each day as riding the bus. If she spends 75 minutes on the bus and the train
yulyashka [42]

Answer:

60 minutes or 1 hour

Step-by-step explanation:

Set x as the amount of time she spends riding the bus

75 = time on bus + time on train

She spends 4 times as long on the train as on the bus so the time she spends on the train is 4x

75 = x + 4x

75 = 5x

x = 15 minutes on the bus

Since she spends 4 times as long on the train, we do 4 x 15 and we get 60 minutes which is 1 hour
