Answer:
There are 56 stuffed animals and 28 mystery boxes in the claw arcade machine
Step-by-step explanation:
Firstly, we assign variables.
Let the number of stuffed animals be x and the number of mystery boxes be y
The probability of selecting a stuffed animal is x/84 while the probability is selecting a mystery box is y/84
Now, since the total probability can be 1:
This means that
x/84 + y/84 = 1 •••••••(i)
Now from the question, we were told that the probability of selecting or winning a stuffed animal is twice that of winning a mystery box
Thus x/84 = 2 * y/84
X/84 = y/42
Let’s substitute this into equation 1
y/42 + y/84 = 1
(2y+ y)/84 = 1
3y/84 = 1
3y = 84
y = 84/3
y = 28
Since x + y = 84
x = 84 - y
x = 84-28 = 56
For 6 1/2 hours, earned money = $78
So, for 1 hour, it would be: 78 / 6 1/2 = 78 / 13/2 = 78*2 /13 = 12
In short, Your Answer would be $12
Hope this helps!
Answer:$600
Step-by-step explanation:
450 divided by 9 equals 50 that’s how much the shirts cost
So if you multiply 50 times 12 you get 600
