Answer:
The original price is $409.5
Step-by-step explanation:
the 2 numbers that you have in this equation are 315 and 30% (or .30)
You want to multiply 315 by .3 to get an answer of 94.5
That's the amount of money that was marked down on the guitar
So you want to add 94.5 to 315 which gives you 409.5
so $409.5 is your answer

Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.
8000km per hour.
96,000/12=8000
