# Tasha wants 25 pounds of a nut mix that she can sell for $5.00 per pound. If she has cashews that sell for$6.50 per pound and pistachio nuts that sell for $4.00 per pound, how much of each should she use? ##### 1 Answer Sep 8, 2015 #### Answer: Cashews = 10 pounds pistachio = 15 pounds #### Explanation: Total nuts = 25 pounds Cashews = x pound pistachio = (25 - x ) pounds $\left(6.5 \times x\right) + \left[4 \left(25 - x\right)\right] = \left(5 \times 25\right)$$6.5 x + \left[100 - 4 x\right] = 125$$6.5 x + 100 - 4 x = 125$$2.5 x = 125 - 100 = 25$$x = \frac{25}{2.5} = 10\$

Cashews = 10 pounds
pistachio = (25 - 10 ) = 15 pounds
