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

Melissa rolls 2 fair dice. The probability of getting a total of 12 is
<u>Solution:</u>
Given, Melissa rolls 2 fair dice and adds the results from each.
We have to work out the probability of getting a total of 12
<em><u>The probability of an event is given as follows:</u></em>
Now, total outcomes = 6 for 1st die 6 for 2nd die = 6 6 = 36.
Now, favourable outcomes = 1 [ since, we have to get a sum of 12, and only one case exists i.e. 6 + 6]
Hence the probability of getting a total of 12 is
