Answer:
The original price of the tent = $320
Step-by-step explanation:
Let the original price be =$ 
Discount offered =
% of the orignal price = 
Original price is $80 more than sale price
Discount = Original price - Sale price = $80
So, we have

We need to solve for
to find original price
Dividing both sides by 

∴ The original price of the tent = $320
X/2=8/9 | *2
x=16/9≈ 1,78
2. 1 $.........1,09 Euro
x$...........157 Euro
x=157*1/1,09≈144,04 $
Answer:
Step-by-step explanation:
1 ) k²-8k = 0
k(k-8)=0
k = 0 or k=8
2) a²+5a=0
a(a+5) = 0
a=0 or a = - 5
3 ) 6n²+5n-25=0
delta = b²-4ac b =5 and a = 6 and c= - 25
delta = 5²-4(6)(-25) = 625 = 25²
n 1 = (-5+25)/12 = 20/12 = 5/3
n 2 = (-5-25)/12 = - 30/12 = -5/2
same method for 4) and 5)
Answer:
.65% / hr = .0065 / hr
2.75 days * 24 hrs / day = 66 hrs
66 hrs * .0065 / hr = .429
So our amount will become
A = A0 ( 1 + .429) = 9700 * 1.429 = 13860
