Question

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.

Answer 1

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

$C = 0.99 + xy + 0.2z$

Cost:

0.3 kilograms of tomatoes, at 3.30 dollars per kilogram.

Thus, the cost starts at:

$C = 0.3*3.3 = 0.99$

y kilograms of cucumbers, at x dollars per kilogram.

Considering this, the cost will now be of:

$C = 0.99 + xy$

0.2 kilograms of carrots, at z dollars per kilogram:

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

$C = 0.99 + xy + 0.2z$
