Kayla's school is selling tickets to a play. on the first day of ticket sales, the school sold 5 senior citizen tickets and 3 child tickets for a total of $69. the school took in $73 on the second day by selling 1 senior citizen ticket and 8 child tickets. find the price of a senior citizen ticket and the price of a child ticket

Senior Citizen Tickets Cost = $9

Child Tickets Cost = $8

Step-by-step explanation:

Let price of senior ticket be "s", and

price of child ticket be "c"

5 senior ticket and 3 child ticket cost 69, so we can write:

Also, 1 senior and 8 child tickets cost 73, thus we can write:

Or

We can put this into 1st equation and get an equation in terms of "c" and solve for c first:

Thus, c = 8

Now,

s = 73 - 8c

s = 73 - 8(8)

s = 73 - 64

s = 9

So,

Senior Citizen Tickets Cost = $9

Child Tickets Cost = $8

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
