Let the present age of student be x
Present of teacher will be 4x
After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20
According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10
So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.

Amanda purchased a 30 year $10,000 bond at par value with a 4% coupon.
We find the coupon amount each year
Coupon amount = actual amount of bond * 4%
= 10,000 * 0.04 = 400
Coupon amount for every year = 400
Total value of coupons for 30 years = 400 * 30 = 12000
$12,000 is the total value of the coupons
Answer:
x= 1
y= -1
Step-by-step explanation:
y=-2x+1
2x-2y=4
substitute for y
2x-2(-2x+1)=4
reduce
2x+4x-2=4
6x=6
x=1
y= -2(1)+1
y= -1
You just do 36*.25=9
Then 36-9=27
$27 is your final price
Hope this helps!

-The perimeter is the length of the line if the whole rectangle was straightened out.
-a rectangle has 2 sets of 2 even sides. The top and bottom width would be equal and the two heights would be equal
Armed with these two facts we know the perimeter would be Side A + Side B + Side C + Side D
9.35 + 9.35 + 6.82 + 6.82 = ?
The actual formula for a rectangle or even a square is
2(length + width)
