Given:
let h be the high quality bean
let c be the cheaper bean
h + c = 160
6h + 3.25c = 160*4.97
6h + 3.25c = 795.20
h = 160 - c
6(160 - c) + 3.25c = 795.20
960 - 6c + 3.25c = 795.20
-2.75c = 795.20 - 960
-2.75c = -164.80
c = -164.80 / -2.75
c = 59.92 or 60 lbs
h = 160 - c
h = 160 - 60
h = 100 lbs
Sarah should blend 60 lbs of cheap coffee bean and 100 lbs of high quality coffee bean.
A is the right option! Because 0.40 should be in second equation with the x to represent the number of stamps multiply by 40 cents.

We are asked to find the number of combinations in which the 4 remaining flowers can be given to 4 flowers.
When she gives the next teacher a flower, there are 4 options. Next, there will only be 3 options since one flower was given away. Next there will be 2 options, and finally there will only be 1 flower left.
This means that there are:
4! = 4 * 3 * 2 * 1 = 24 ways to give the remaining flowers.
The answer is 24.
