Wyatt is making a salad using tomatoes, cucumbers, and carrots. This table gives the cost, per kilogram, of each ingredient, and the amount, in kilograms, that Wyatt uses: Ingredient Price per kilogram Amount
Tomatoes 3.30dollars per kilogram 0.3
Cucumbers x dollars per kilogram y kilograms
Carrots z dollars per kilogram 0.20
The total amount Wyatt spends on ingredients is C dollars.
Write an equation that relates x, y, z, and C.

According to the given information, we build the equation for the cost. After we build the equation, the equation that relates these measures is:

Cost:

0.3 kilograms of tomatoes, at 3.30 dollars per kilogram.

Thus, the cost starts at:

y kilograms of cucumbers, at x dollars per kilogram.

Considering this, the cost will now be of:

0.2 kilograms of carrots, at z dollars per kilogram:

Now, we have to consider this for the cost, so:
