We want to find and solve an equation that tells us the number of pounds of raisins that we need to add to a mixture to get to a desired price.
We will see that we need to add 3 pounds of raisins.
We know that:
- Granola costs $3.25 per lb
- Raisins cost $6.50 per lb.
If we mix M pounds of raisins with 10 pounds of granola, the total mass will be:
M + 10
The price of this will be:
M*$6.50 + (10)*$3.25
And we want the price of this mixture to e $4.00 per pound, then we have:
M*$6.50 + (10)*$3.25 = (M + 10)*$4.00
Now we need to solve the above equation for M.
M*$6.50 + $32.50 = M*$4.00 + $40.00
M*$6.50 - M*$4.00 = $40.00 - $32.50
M*($6.50 - $4.00) = $7.50
M*$2.50 = $7.50
M = ($7.50)/($2.50) = 3
M = 3
This means that we need to add 3 pounds of raisins.
