Allie orders candles from an online company that offers flat rate shipping. She placed an order for 4 candles for $35. A few months later, she placed an order for 12 candles
for $95. Write an equation in point-slope form to model the total cost, y, for ordering x
candles. How much is shipping?
y - 95 = 7.5 (x - 12) y + 35 = 7.5 (x + 4): y + 95 = 7.5 (x + 12) Y - 35 = 7.5 (x - 4):
; shipping is $7.50 shipping is $7.50 ; shipping is $5
shipping is $5

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
