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? 75p + 150 (10) = 100 (p + 10) 75 (p + 10) + 150 (10) = 100 (p + 10) 75p + 150 = 100 (p + 10)

If p represents the number of pounds of cashew nuts required, the equation of the 1st selection is appropriate.

It tells that the prices of the contributing nuts add to give the price of the mixture, just as you want.
