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:
Step-by-step explanation:
If f(n) = 8n - 3
f(5) = 8(5) - 3
= 40 - 3
= 37
First subtract 4 from btoh sides of the equation
4 - 4 - 2x < 6-4
-2x < 2
Now divide both sides by -2
x > -1
NOTE: when dividing by a negative as above the inequality sign is flipped.
Answer:
x=7-13
Step-by-step explanation:
Distribute the negative.
- 8 - 2a =
Factor out -2
