Answer:
$2.8
Step-by-step explanation:
Given :
Marion buys 3 pounds of granola for $3 per pound, and 0.75 pounds of raisins for $2 per pound.
The equation 3(3) + 0.75(2) = (3 + 0.75)x models the situation, where x is the price per pound of the trail mix.
To Find: What is the price of the trail mix?
Solution:
[tex]3(3) + 0.75(2) = (3 + 0.75)x[/tex]
Where x is the price per pound of the trail mix.
[tex]9+ 1.5 = (3.75)x[/tex]
[tex]10.5 = (3.75)x[/tex]
[tex]\frac{10.5}{3.75}=x[/tex]
[tex]2.8=x[/tex]
Hence the price of the trail mix is $2.8 per pound.
