Each student should make at least $25 to reach their goal.
Answer:
2x³ - 17x² + 13x + 11
Step-by-step explanation:
(2x + 1)(x² - 9x + 11) Distribute the 2x then the 1
2x³ - 18x² + 22x + x² - 9x + 11 Combine like terms
2x³ - 17x² + 13x + 11

Given parameters:
Mark up percentage = 150%
Original cost = $488
Sales tax = 5%
Unknown:
His total cost = ?
Solution:
Marking up a good is the amount a sell adds to a product which makes its selling price usually for a profit.
Since the emerald was marked up by 150%;
New cost = (1 + 1.5) x $488 = $1220
Now, the additional tax was 5%;
Tax =
x 1220 = $61
So, the total cost = New cost + tax = $1220 + $61 = $1281
32 - 7 = 25/5 = 5
so, we have 5 products being purchased, since the 7 sec check-out doesn't count as product time.

9 Polyester fill and 5 down fill sleeping bags were sold.
Step-by-step explanation:
Let,
Polyester fill sleeping bags = x
Down fill sleeping bags = y
Price of 1 polyester fill bag = $79
Price of 1 down fill bag = $149
According to given statement;
x+y=14 Eqn 1
79x+149y=1456 Eqn 2
Multiplying Eqn 1 by 79
![79(x+y=14)\\79x+79y=1106\ \ \ Eqn 3\\](https://tex.z-dn.net/?f=79%28x%2By%3D14%29%5C%5C79x%2B79y%3D1106%5C%20%5C%20%5C%20Eqn%203%5C%5C)
Subtracting Eqn 3 from Eqn 2
![(79x+149y)-(79x+79y)=1456-1106\\79x+149y-79x-79y=350\\70y=350](https://tex.z-dn.net/?f=%2879x%2B149y%29-%2879x%2B79y%29%3D1456-1106%5C%5C79x%2B149y-79x-79y%3D350%5C%5C70y%3D350)
Dividing both sides by 70
![\frac{70y}{70}=\frac{350}{70}\\y=5](https://tex.z-dn.net/?f=%5Cfrac%7B70y%7D%7B70%7D%3D%5Cfrac%7B350%7D%7B70%7D%5C%5Cy%3D5)
Putting y=5 in Eqn 1
![x+5=14\\x=14-5\\x=9\\](https://tex.z-dn.net/?f=x%2B5%3D14%5C%5Cx%3D14-5%5C%5Cx%3D9%5C%5C)
9 Polyester fill and 5 down fill sleeping bags were sold.
