Answer:
The amount after 1 year is $ 1060 .
Step-by-step explanation:
The amount after 1 year on $1,000 invested at 6% per year on simple interest
is given by,
$ ![1000 \times (1 + \frac{6}{100})](https://tex.z-dn.net/?f=1000%20%5Ctimes%20%281%20%2B%20%5Cfrac%7B6%7D%7B100%7D%29)
= $ (1000 + 60)
= $ 1060
We know that, if,
Principal = P unit
Rate of annual simple interest = R%
Time = T year
then, amount, A =
unit
Start by finding the area of one of the stools with this formula:
A=(3.14)(12)(12)
Then multiply that answer by five, since there are 5 stools.
Hope this helps :) good luck
Answer:
(8, 17)
Step-by-step explanation:
y= 3x -7 -----(1)
y= 2x +1 -----(2)
Substitute (1) into (2):
3x -7= 2x +1
Being x terms to one side, constant to the other:
3x -2x= 7 +1
x= 8
Substitute x= 8 into (2):
y= 2(8) +1
y= 16 +1
y= 17
∴ The solution is (8, 17).
