Answer:

The equation is:

        [tex]j/g=5/2[/tex]

Or, what is equivalent:

        [tex]j=5g/2[/tex]

Explanation:

This is the table that shows the amount of lemon juice and sugar needed to make three different-sized batches of lemonade using the same recipe:

                        Lemon juice (mL)       Sugar (g)

Batch A               500                            200

Batch B                750                            300

Batch C              1500                            600

You need to write an equation to describe the relationship between j, the amount of lemon juice in mL and s, the amount of sugar in g.

Calculate some ratios, to determine the kind of relation between the amount of juice and the amount of sugar in the recipe.

  • Batch A: lemon juice / sugar = 500 / 200 = 5/2

  • Batch B: lemon juice / sugar = 750/300 = 5/2

  • Batch C:  lemon juice / sugar = 1500/600 = 5/2

Hence, the amount of juice, j, and the amound of sugar, s, are proportional and the constant of proportionality is 5/2. From this, the equation is:

        [tex]j/g=5/2[/tex]

Or, what is equivalent (solving for j):

        [tex]j=5g/2[/tex]

Answer:

j=2.5s
