Although not so common now, consider a phone plan that does not have unlimited texting. Your base plan costs you $30 a month and

each text sent or received is only 12 cents. Write an equation to describe the total monthly cost of your bill with x text messages and y cost.
In one month 217,000 messages were sent between two brothers in Philadelphia. What was their approximate bill? (This is a true story!)

Answer:

The bill will be $26070.

Step-by-step explanation:

Your base plan costs you $30 a month

And each text sent or received is only 12 cents or $0.12.

Let the messages sent be = x

So, cost for messages become = 0.12x

Let total bill cost be = y

Now, total bill will comprise of monthly plan charges plus message charges.

So, equation forms:

y=30+0.12x

Now, given is that In one month 217,000 messages were sent between two brothers in Philadelphia.

So, their approximate bill will be :

y=30+0.12(217000)

=>y=30+26040

=> y = 26070

Therefore, bill will be $26070.

Jobisdone [24]

Answer:

P(Service\ Brokerage\ or\ Online) = 66\%

Step-by-step explanation:

Given

P(Service\ Brokerage) = 60\%

P(Online) = 30\%

P(Both) = 24\%

Required

Determine P(Service Brokerage or Online)

In probability:

P(A\ or\ B) = P(A) + P(B) - P(Both)

In this case:

P(Service\ Brokerage\ or\ Online) = P(Service\ Brokerage) + P(Online) - P(Both)

Substitute values:

P(Service\ Brokerage\ or\ Online) = 60\% + 30\% - 24\%

P(Service\ Brokerage\ or\ Online) = 66\%

<em>Hence, the required probability is 66%</em>

3 hours = 26.25

---------------------------------
Find wages for 1 hour :
---------------------------------
1 hour = 26.25 ÷ 3 = 8.75

---------------------------------
Find wages for 8 hours :
---------------------------------
8 hours = 8.75 x 8 = $70

---------------------------------
Find wages for a week :
---------------------------------
$70 x 7 = $350

---------------------------------
Salvador
---------------------------------
2 hours = $15

---------------------------------
Find 1 hour :
---------------------------------
1 hour = $15 ÷ 2 = $7.50

---------------------------------
Find 8 hours :
---------------------------------
8 hours = $7.50 x 8 = $60

---------------------------------
Find 1 week :
---------------------------------
1 week = $60 x 5 = $300

---------------------------------
Define x :
---------------------------------
Let x be the number of weeks needed 

---------------------------------
Construct equation :
---------------------------------
350x = 300x + 1000

---------------------------------
Solve for x :
---------------------------------
350x = 300x + 1000

---------------------------------
Take away 300x from both sides :
---------------------------------
50x = 1000

---------------------------------
Divide by 50 :
---------------------------------
x = 20

------------------------------------------------------------------
Answer: It will take 20 weeks.

Pavlova-9 [17]

H = 3t + 8

Step-by-step explanation:

Since the plant has an initial height of 8 inches, this will be added to the amount it grows each month.

3t will represent how much it grows t months after he bought the plant, since it grows 3 inches each month.

So, the equation will be H = 3t + 8
