Question

Cashews cost $5 per pound and peanuts cost $1.50 per pound. How many pounds of cashews should be mixed with peanuts to get a mixture of 32 pounds that will cost $4 per pound? Round to the nearest tenth

Answer 1

Total Cost = Amount of pounds x Cost per Pound = 32 x 4 = 128
Let Pounds of Cashew = C.
Total Pounds = Pounds of Cashew + Pounds of Peanuts
32 = C + Pounds of Peanuts
Pounds of Peanuts = 32 - C

Total Cost = 128 = Cost of Peanuts + Cost of Cashews
128 = (32 - C)(1.5) + (C)(5)
128 = 48 - 1.5C + 5C
128 = 48 +3.5C
C = ?
