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.

In six months the membership at a fitness center went from 3,500 to 4,200. what was the percent of increase in the membership?

slega [8]

It is definitely C: 20%

Subtract the original value from the new value, then divide the result by the original value then multiply the result by 100 and it will give you the answer

$\frac{4200 - 3500}{3500} \times 100$
$\frac{700}{3500} \times 100$
$0.2 \times 100 = 20\%$
