Math homework

Recommended Posts

Tiana’s mom promises to pay Tiana to clean out the garage. She figures that the first week will be the hardest, but that it will get gradually easier, so she decides to pay Tiana $100 the first week, and then 75% of the previous week’s amount for each of the following weeks. However, when the amount drops below $25, Tiana will earn a steady income of $25/week. How much will Tiana earn after 10 weeks? Round to the nearest dollar.

You have 5 minutes to answer this. Winner gets senpai to notice him! (Suckers!)

Thank you. You have saved save Senpai from a band grade in SAT Prep! Senpai notices you.

You are NOT senpai. Those who have come before you and know how to arrive at the correct answer are senpai.

How about you learn how to solve it?

[1]= $100

[2]= $75

[3]= .75*$75= 56.25

[4]= .75*.75*$75= 42.1875

[5]= .75*.75*.75*$75= 31.640625

[6]= .75*.75*.75*.75*$75 = 23.73046975 -> $25, since it can't go less than 25$

[7]= 25

[8]= 25

[9]= 25

[10]=25

10 week total= Sum [1] through [10] = 100 + 75 + 56.25 + 42.19 + 31.64+ 25 + 100= 430.08 -> $430

What part gave you difficulty? How to arrive at the amount paid each week or what?

Honesty, I had it figured out before I seen all of the answers. Hahahaha.

So basically..... you wasted everyone's time, *sigh*....

Yes and no, I did need help with that math problem, but I couldn't wait for a while for someone to answer. I tried my best to answer the question. I later checked back to see if anyone actually answer. To my surprise a few kind people actually took the time to help a fellow Reborn member and I thank them for that.
