(b) A field of rectangular shape has area $A$ meters$^2$, with one side of $w$ meters and another $10$ meters bigger.
(c) $x$ is an amount of large cheeseburgers and $y$ stands for amount of large hamburgers. A single cheeseburger costs $10.50\$$ and a single hamburger costs $11.75\$$. $C$ represents total amount of money to pay for given amount of hamburgers and cheeseburgers.
Work Step by Step
(a) $C=20,000 + 4.50x$
In a factory, each worker makes specific parts for a car. $C$ represents semi-annual salary of each worker. Salary for each worker is fixed $20,000\$$ and extra $4.50\$$ for each extra piece of item. Amount of total extra pieces made is represented by $x$, while total salary is $C$
(b) $A = w(w+10)$
A field of rectangular shape has area $A$ meters$^2$, with one side of $w$ meters and another $10$ meters bigger.
(c) $C=10.50x+11.75y$
$x$ is an amount of large cheeseburgers and $y$ stands for amount of large hamburgers. A single cheeseburger costs $10.50\$$ and a single hamburger costs $11.75\$$. $C$ represents total amount of money to pay for given amount of hamburgers and cheeseburgers.
