Originally Posted by cyrus23 can someone fix the format of my question? its not showing up properly I've edited your post so it renders correctly. Dollar signs have a special meaning on this forum - they are used for typesetting math (latex). If you precede each dollar sign with a \ you won't have a problem. Also, we ask that our users show their progress (work thus far or thoughts on how to begin) when posting questions. This way our helpers can see where you are stuck or may be going astray and will be able to post the best help possible without potentially making a suggestion which you have already tried, which would waste your time and that of the helper. Can you post what you have done so far? 3. Thread Author thank you! well Im pretty sure im doing it wrong because im not sure how to do this question but this is what i have so far 2790 (1-7) 2790 (0.93) 2594.7 1920 (1-4) 1920 (0.96) 1843.2 4. Thread Author can someone please answer and help me? 5. Hello cyrus23, MHB rule #1 states: Originally Posted by MHB Rules No bumping.

If you want to draw attention to an unanswered thread, then post something of value such as further progress. It is also forbidden to bump one thread by drawing attention to it in a different thread. This rule is designed to make MHB more useful and efficient for everyone. When you bump a thread this adds no content and yet draws attention to it, causing people to possibly take time to see what has been added only to find that no content has actually been added. This can waste the time of our helpers, and this time is very valuable. Any time we can save on the part of the volunteer helpers would, I hope you can see, help you in the long run! So, if you could please help us help you in this way, by not bumping, we would greatly appreciate it. We ask that you be patient and wait for someone to reply. You are of course welcome to post your progress or additional thoughts that have occurred in the meantime. We ask that you keep this policy in mind in the future. We also ask that you consider how much less efficient MHB would be if this posting behavior was allowed. greg1313 6.

You must read the discount terms very carefully.

It says: $\displaystyle 7/10,\;4/20,\;n/30.$

$\displaystyle \begin{array}{ccc}\text{This means:} & 7\%\text{ discount if paid within 10 days,}\\ & 4\%\text{ discoiunt if paid within 20 days,} \\ & \text{net (balance) is due within 30 days.} \end{array}$

The merchant paid \$2790 on Jan 12. This is within 10 days; he is entitled to a 7% discount. The next step is a bit tricky. He paid \$2790, which is worth: $\displaystyle \frac{\$2790}{ 0.93} = \$3000$

Then he paid \$1920 on Jan 21. This is within 20 day; he is entitled to a 4% discouint. He paid \$1920, which is worth: $\displaystyle \frac{\$1920}{0.96} = \$2000$

His final balance is: $\displaystyle \$7000 - 3000 - 2000 \,=\,\$2000$
