It's simple, if you understand. Let's see.
y= the total cost of everything.
x=the total amount of hours spent on the contract.
It's simple!!
$140 is the base line. It never changes. So, we begin with $140. Every hour Luigi works, he charges $25. So $140+$25x. Finally, our total amount is y, so $140+$25x=y. abracadabra!!
Answer:
C.) 514.75
Step-by-step explanation:
r = 24/16 = 1.5
r = 36/24 = 1.5
r = 54/36 = 1.5
16 + 24 + 36 + 54 + 81 + 121.5 + 182.25 = 514.75
or use:
Sn = a[ (1-r^n) / (1 - r) ]
S7 = 16[ (1 - 1.5^7) / (1 - 1.5) ]

im probably wrong im so sorry
Use the
Binomial expansion theorem to find and simplify each
term.
Man that was a lot to type out, hopefully i helped, and Gosh I hope I get a brainly for all that freaking typing. hehe~ ^.^
