Answer:
No, this is not the correct amount.
Step-by-step explanation:
Assuming this purchase is being made in the USA, the average federal tax rate on purchased goods is between 2.9% and 7.25% of the price. Let's be generous and assume that wherever you're making this purchase, the sales tax is 7.25%.
7.25% of 11 = .7975, or .80 cents. Add that to 11 to get $11.80.
The extra 91 cents tax is around 12.09% tax which is a lot higher than normal. You're being ripped off!

Answer:64mi/hour
Step-by-step explanation:
V=speed × time
V=s×t .....equation (1)
v=576
for taking one hour: t-1
speed is: s+8
From equation(1)
V=(s+8)(t-1)
(s+8)(t-1)=576
Expand the bracket
st-s+8t-8=576
Substitute the value of st which is 576
576-s+8t-8=576
Collect the like terms
-s+8t-8=0
s=8t-8
Subtitude into the value of s
576= (8t-8)×t
576=8t^2-8t
8t^2-8t=576
8t^2-8t-576=0 (divide both by 8)
t^2-t-72=0
By factorization method
Product is (-9 and 8)
(t-9)(t+8)=0
t=9 or t=-8
V=s×t
576=s×9
9s=576
s=576/9
s=64mi/hour
