How many pounds of cashew nuts worth 75 cents a pound must be mixed with 10 pounds of pecans worth $1.50 a pound to make a mixture worth $1.00 a pound? Which of the equations could be used to solve for p, the pounds of cashew nuts? 75 p + 150(10) = 100( p + 10)
75 p + 150 = 100( p + 10)
75( p + 10) + 150(10) = 100( p + 10)
