Cashews sell for $4.00 per pound and peanuts for $1.50 per pound. The peanuts didn't sell well, so in order to sell 60 lbs of peanuts the manager decided to mix 60 lbs of peanuts w/ cashews and sell the mixture for $2.50 per pound. How many lbs cashews should be mixedto ensure no change in profit?
I thought the equation would be
4c + 1.50p = 2.50
c + 60p = 100 ?
or should I multiply 2.50(60)

total cost=sum of costs
2.50(c+p)=4c + 1.50p
and p is given as 60
solve for c 
A store is selling two mixtures of nuts in 20ounce bags. The first mixture has 15 ounces of peanuts combined with five ounces of cashews, and costs $4.25. The second mixture has five ounces of peanuts and 15 ounces of cashews, and costs $6.75. How much does one ounce of peanuts and one ounce of cashews cost?
