german

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.

Howmany blue pens should he order ?

photoshop1234 [79]

Answer:

Step-by-step explanation:

Given :

Total number of people : 36

Ratio of people who prefer red to blue

Red : Blue = 3 : 9 = 1 : 3

according to the ratio, for every 4 people, 1 prefers red and 3 prefers blue.

Expressed mathematically:

People who prefer blue = 3/4 of the total number of people

In our case, total number is 36 hence,

People who prefer blue (and hence the number of blue pens he should order),

= 3/4 x 36 = 27
