To determine the cost of 1 pound of potato, simply divide the 10-pound sack of potatoes cost by the number of pounds, 10. That is,
c = $6.55 / 10 = $0.655
Thus, each pound of potatoes cost nearly $0.66. The answer is letter B.
replace the numbers inside () for x
f(4) = -4(4)-3 = -16 -3 = -19
G(-4) = 2(-4)^2 -3(-4) = 44
The correct answer is 2x + 8.
X1 + X2 + X3 <27 for all Xi> 0
X1 + X2 + X3 <27 for all Xi> 0, X2 >/ 5
