Range = 10 - 0 = 10
Q2 = (6 + 6)/2 = 6 (13th + 14t)/2
Q1 = 5 7th
Q3 = 8 20th
IQR = Q3 - Q1
= 8 - 5
= 3

Answer:
3 meals
Step-by-step explanation:
The card costs $6, so we will subtract that from $15 because it is the starting amount. Karla can't buy these meals for $3 without $6. Anyways, 15-6 is 9. Each meal costs $3 so we'll then divide 9 by 3, which gives us our answer: she bought 3 meals.
520 CD's because of the 9 months and we add 30 time 9 we erase the 0 and multiply the 3 with the 9 it will be 27 right we add the zero because the originla number is 30
