A long distance telephone company offer two plans . The deluxe plan cost $30 a month and offers unlimited long distance calling.
Gnesinka [82]

Answer:

399 minutes a month

Step-by-step explanation:

As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.

The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).

The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.

Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.

aleksley [76]

Answer:

  an = n -27

Step-by-step explanation:

The general term (an) of an arithmetic sequence is given by the formula ...

  an = a1 + d(n -1)

where a1 is the first term and d is the common difference.

Your sequence has a first term of a1 = -26 and a common difference of d = 1. Putting these values into the formula gives ...

  an = -26 + 1(n -1)

This can be simplified to ...

  an = n - 27
