Answer 1

Answer:

Dependent variable: Amount of oranges ($y$), measured in pounds.

Independent variable: Money ($x$), measured in US dollars.

Equation: $y = 1.15\cdot x$

Step-by-step explanation:

According to the statement, Maria pays money to buy oranges at the grocery and there is a direct proportionality between money ($x$), measured in US dollars, and the amount of oranges ($y$), measured in pounds. That is:

$y \propto x$

$y = k\cdot x$

Where $k$ is the proportionality constant, measured in US dollars per pound.

The dependent variable is the amount of oranges ($y$), whereas money ($x$) represents the independent variable. If we know that $k = 1.15\,\frac{USD}{pd}$, then the equation is:

$y = 1.15\cdot x$

In a nutshell, the answer is:

Dependent variable: Amount of oranges ($y$), measured in pounds.

Independent variable: Money ($x$), measured in US dollars.

Equation: $y = 1.15\cdot x$
