Mean: so basically you add up all the numbers (5+12+1+5+7=30) and divide the sum (30) with how many numbers there are (5) so 30/5=6
mode: mode is numbers repeated, since there are two 5's it is the mode (you may also have multiple modes)
Its C because the 18in is the height, the 12in is the width, the 24in is the length. Which you just multiply together.
150 lower level
200 upper level
Let x = lower level and y = upper level. You can then set up an equation for cost as:
35x + 25y = 10,250
and the equation for total tickets as:
x + y = 350.
Solve using any method.
2(2.5-(5/6))
2(1 2/3)
