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
