I need help finding the percentage to this word problem!

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 = 144.50and 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

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )
