Step-by-step explanation:
<u>Step 1: Define</u>
3x < 39
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 3 on both sides: x < 13
Here we see that any value <em>x</em> smaller than 13 would work as solution to the inequality.

Answer:
Each pack of chicken costs $8 and each pack of beef costs $9.24.
Step-by-step explanation:
This question can be solved using a system of equations:
I am going to say that:
x is the cost of each pack of chicken.
y is the cost of each pack of beef.
2 packs of chicken and 3 packs of beef for $42.50.
This means that 
5 packs of chicken and 6 packs of beef for $94.25.
This means that 
We have to solve the following system:


I will use the addition method, multiplying the first equation by -2, and adding to the second


-4x + 5x - 6y + 6y = -85 + 94.24
x = 9.24.
And




Each pack of chicken costs $8 and each pack of beef costs $9.24.
