57 children tickets were sold on Saturday.
You could set this up as a system of equations.
x + y = 155
6.00x + 9.90y = 1312.20
First step is multiplying the first equation by -6 to use the elimination method.
-6.00x + -6.00y = -930
6.00x + 9.90y = 1312.20
The positive and negative 6x cancel out until you are only left with the y.
Combining them would make your equation...
3.9y = 382.2
Next you would divide by 3.9 on both sides to get the y by itself.
The result of that would be y = 98. Which means 98 adult tickets were sold. Then you would plug y into either of the equations to solve for x.
Answer:
It increases the mean value of the prizes
Step-by-step explanation:
If you order the numbers from the lowest to the highest, the median is the number placed in the middle of the ordered list. In this case, there are values repeated many times (there are 100 values, $1 is repeated 44 times and $5 is repeated 25 times, so $5 is the mean), then the presence of a high value with only one presence doesn't modify this median.
On the other hand, the mean is always affected but all data set, given that $100 is the highest value, the mean will increase.
