Answer:
Step-by-step explanation
Each week a discount of 15% of the previous week.So the price will be 85% of the previous week (17/20 of the previous price)
We multiply the price from the previous week by 0.85 to obtain the new price
200 x 0.85 = 170
170 x0.85 = 144.50.....and so on
3)$ 122.82
4$)104.40
5).$88.74
6)$75.42
The shoes will be less than half in week 5
DECAY
The friend is not right
$30 less was only the first week
Each week the saving will be 85% of the previous week. But the shoes will not be free in 2 months On the week 8 the price will be $54.50
Answer:
$7.23
Step-by-step explanation:
(2 x 2.49) + (3 x .75) = 4.98 + 2.25 = $7.23
Answer:
undefined
Step-by-step explanation:
Becouse any number under a root sign that is negative does not give any answer.Therefore it doesn't exist in real number system.
R = 11-2m
S = n+5
T = -m-3n+8
---------------------------
Add up S and T to get...
S+T = (n+5)+(-m-3n+8)
S+T = n+5-m-3n+8
S+T = -m+(n-3n)+(5+8)
S+T = -m+(1n-3n)+(5+8)
S+T = -m+(-2n)+(13)
S+T = -m-2n+13
---------------------------
Subtract that result from R
R - [S + T]
11-2m - [-m-2n+13]
11-2m +m+2n-13
(-2m+m) + (2n) + (11-13)
(-2m+1m) + (2n) + (11-13)
(-1m) + (2n) + (-2)
-m + 2n - 2
---------------------------
---------------------------
The final answer is -m + 2n - 2
