Answer:
B = 87.08 pounds @ $0.32
A = 22.92 pounds @ $0.08
Step-by-step explanation:
given,
cost of beans (A)= $ 0.08/pound
and another beans cost (B) = $ 0.32 /pound
total weight of the pound = 110 pound
selling price of mixture = $ 0.27/pound
cost of each bean = ?
A + B = 110
A = 110 - B-------(1)
0.08 A + 0.32 B = 0.27 x 110
0.08 A + 0.32 B = 29.7
Putting value of A
0.08(110 - B) + 0.32 B = 29.7
8.8 - 0.08 B + 0.32 B = 29.7
0.24 B = 20.9
Answer: x=55 y=145
x=55
35+90=125
125-180=55
y=145
180-35=145
I hope this is good enough:
2 - (-4) + (-y)
Substitute y = 7 to the expression:
2 - (-4) + (-7) = 2 + 4 - 7 = 6 - 7 = -1
