Jill wants to mix almonds and peanuts so that the retail price will be $4.90 per pound.
Almonds cost $7 per pound, and peanuts cost $3 per pound.
She wants to add 20% to the base price for her own profit, after which she will have the final retail price.
In what percentage ratio should she mix the almonds and the peanuts?
:
Assuming the the final retail price will be 1.2*4.90 = $5.88 a pound including the 20% profit
:
Assume there is a mix of 10 lb
:
Let x = amt of Almonds
then
(10-x) = amt of peanuts
:
3(10-x) + 7x = 5.88(10)
30 - 3x + 7x = 58.8
4x = 58.8 - 30
4x = 28.8
x = 28.8/4
x = 7.2 lb of almonds
then
10 - 7.2 = 2.8 lb of peanuts
:
" In what percentage ratio should she mix the almonds and the peanuts? "
* 100 = 72% almonds
* 100 = 28% peanuts
