Answer:
$107.50
Step-by-step explanation:
$3.50 = 1 STUDENT
$5.00 = 1 ADULT
TWENTY FIVE STUDENTS = $3.50 × 25 = $87.50
FOUR ADULTS (ONE TEACHER AND THREE PARENTS) = $5.00 × 4 = $20.00
TOTAL COST = $87.50 + $20.00 = $107.50

Answer:
0.8
Step-by-step explanation:
3/4 =0.75
~0.8(to 1s.f)
Okay so you put the numbers in order:
70, 74, 81, 82, 83, 91, 94.
Then you find the median which will be Q2:
82.
Once you have the total median, you find the midpoint of the first and last part:
70, 74, 81. Midpoint/Q1=74
83, 91, 94. Midpoint/Q3=91
Now that you have that, you subtract Q3 and Q1.
91-74=17
17 is your IQR.
