Answer 1

Textbooks... Workbooks.
.
I was once homeschooled, ya know. 
.
Let me walk you through the problems.
.
First of all...
.
we know the area of the garden. In order to find how many cups of fertilizer we need, we need to find THE AREA. Then, it's just a matter-of-fact of just multiplying the area by 1/8.
.
2. Information not needed? OF COURSE!! The money. Why we need money in this problem?! We find NUMBER OF CUPS, not MONEY NEEDED.
.
3. I need to determine how much cups of fertilizer I need. The answer? Oh, find the area. IT's 9 1/3 multiplied by 12, by the way. Then multiply the area by 1/8. BOOM!!
.
Need any more help, ask away!!
