Answer:
-136
Step-by-step explanation:
This series can be written as: (14 - 3*0) + (14 - 3*1) +...+ (14 - 3*n)
The sum of the first 16 terms is:
14*16 <u>- 0 - 3 - 6 - 9 -...</u> = 224 - 360 = -136
This underlined bit can be calculated in many ways, I personally used my calculator, but there are formulas to do so.
<span>I think the easiest way to answer all of these is to just go ahead and find the equation of the line first.
I'm pretty sure that by the time you reach this problem, you've learned to find
the
equation of a line that passes through two given points. You have two
points: (2, 100) and (5, 205). The equation of the line through them
is [ y = 35x + 30 ].
6). The initial membership fee ... the cost for walking in the door and signing up,
before any months, is $30. (Also the y-intercept.)
7). The cost per month is $35. (The slope of the line.)
8). We already did that, up above. [ y = 35x + 30 ].
9). 'x' in the equation is the number of months.
There are 12 months in one year.
y = 35(12) + 30 = $450</span>
