b. 3 lbs Kenya and 7 lbs French Roast
c. 1.5 lbs Kenya and 8.5 lbs French Roast
d. 4 lbs Kenya and 6 lbs French Roast

Answer 1

B and D are wrong.

Answer 2

Answer is A

Answer 3

2.5 x 15 = 37.5

7.5 x 8 = 60

60 + 37.5 = 97.5

Answer 4

x=kenya beans pounds
y=french roasts pounds
Now, create a system of equations. You have 2:
1. x+y=10
2. 15x+8y=97.50
Then, solve system of equations.
y=10-x
15x+8(10-x)=97.50
7x+80=97.50
7x=17.5
x=2.5.
plug into y=10-x.
y=7.5.

2.5 lbs Kenya and 7.5 lbs French roast.
