8 Week Prep Course for the AMC 8: Week 3
I already asked Mr. David about this: my score for the Week 3 is wrong. I got 8 out of 10 right(not including the file for show my work), but my score was 40/100. Then I rechecked it and on the 6th problem, I got the right answer, but the computer marked me wrong. I think there is a mistake. Can someone recheck my answers? For the other question I got wrong, #4, I don't know how to set up the equation. Can someone tell me how to set the equation for it?
Sincerely,
Amber
Hi Amber,
Remember showing your work counts for 50% of the grade of the assignment,
Question 6 should be fixed now, it seems you included a "$" sign and the system did not recognize your answer as correct. Make sure to include only numbers in your short response questions.
For question 4, try working backwards. For example, since after reading $\frac{1}{3}$ of the remaining pages and 18 more there were 62 pages left to read, $62 + 18 = 80$ pages makes for $1 - \frac{1}{3} = \frac{2}{3}$ of the pages left to read after day 2, that is, $80 \div \frac{2}{3} = 120$ pages.
