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!!

Answer:
Step-by-step explanation:
We are given that Ben has a cell phone plan that provides 200 free minutes each month for a flat rate of $39.
We are also told that For any minutes over 200, Ben is charged $0.35 per minute.
let x be the minutes used each month
So, if 
So, coat will be $39
If 
So, Ben is charged $0.35 per minute
So, when
So, charge = 
So, the piecewise functions accurately represents charges based on Ben's cell phone :
Equation 1. N+D=500
equation 2 5N+10D=3000
This is for equation 1
N=500-d
Substitute into equations 2 and solve for D
5N+10D=3000
5(500-D)+10D=3000
2500-5D+10D=3000
5D=500
D=100
Lets go back the equation 1
N=500-D
N=500-100
N=400
there are 400 Nickles and 100 Dimes
