7. If the concert handed out 208 wands and some wands were red wands and some were green wands. The ratio of red wands to green wands is 1:3. How many fans were given green wands?

red = 52

Green = 156

Step-by-step explanation:

The 208 has to be divided by 4.

Three wands = 3 parts

The read wands = 1

3x + x = 208               Combine terms

4x = 208                     Divide by 4

x = 208/4

x = 52

Now the red wands = 52

The Green wands   =156   (3 times 52)

Total                           208    Just as it should

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)
