Answer:
25
Step-by-step explanation:
Let x is the amount of $11 per pound coffee
then the equation will be,
11x + 3(30) = 5 (x + 30)
11x + 90 = 5x + 150
11x - 5x = 150 - 90
6x = 60
x = 10
So, $10 is the amount of $11 per coffee that should be added
#3 no about 25%are longer than 2 1/2 hrs.
#4 no can't tell individual data items on a box and whisker plot.
by the way number 1 is 92 mins.
To find this answer you first calculate what 3 odd numbers give you 9. These come out to 1+3+5. Then you just test it out which would then give you 21+23+25 = 69
