Mnenie [13.5K]
Given that a <span>store is selling two mixtures of nuts in 20-ounce bags: peanuts and cashews.

Let the cost of one ounce of peanut be x and the cost of one ounce of cashew be y, then

Given that </span>t<span>he first mixture has 15 ounces of peanuts combined with five ounces of cashews, and costs $4.25 implies that 15x + 5y = 4.25

Also, given that </span>t<span>he second mixture has five ounces of peanuts and 15 ounces of cashews, and costs $6.75 mplies that 5x + 15y = 6.75

To obtain the cost of </span><span>one ounce of peanuts and one ounce of cashews, we solve the two equations above, simultaneously:
15x + 5y = 4.25 - - - (1) \\ 5x + 15y = 6.75 - - - (2) \\  \\ (1)\times3\Rightarrow45x+15y=12.75 - - - (3) \\  \\ (2)-(3)\Rightarrow-40x=-6 \\  \\ \bold{x= \frac{-6}{-40} =0.15} \\  \\ From\ (1):15(0.15)+5y=4.25 \\  \\ 5y=4.25-2.25=2 \\  \\ \bold{y= \frac{2}{5} =0.4}

Therefore, </span><span>one ounce of peanuts and one ounce of cashews cost $0.15 and $0.40 respectively.</span>
