Answer:

8 packages

8 jars of sauce

Step-by-step explanation:

As you need just the same amount of pasta and sauce, you only need to create an equation, you can represent the sauce with an x and the pasta with a Y, so your equation would be:

3x + 1y= 36

since X=Y in number your new equation would be:

3x+ 1x=36

4x=36

x=[tex]\frac{36}{9}[/tex]

x=9

The other equation would be:

1.5x + 1y= 20

Since x equals y the equation will end up like this:

1.5x+1x=20

2.5x=20

x=8

Since 8 is the number that best suits the needs for the carying capacities, and you´ll end up with 3 extra bucks, but you cant buy the 9 and 9 and then can´t carry them in the backpack.
