Question

1. a farmer sells eggs for $2.50 per dozen. which equation represents the total revenue (r) from selling x dozen eggs?

a. $r = 2.50x$
b. $r = 5x$
c. $r = 5 + 2.50x$
d. $r = 2.50 + 5x$

Explanation:

Step1: Recall revenue formula

Revenue \( R \) is price per unit times number of units. Here, price per dozen is \( \$2.50 \), and number of dozen is \( x \).

Step2: Formulate the equation

Using \( R=\text{price per dozen} \times \text{number of dozen} \), substitute price \( = 2.50 \) and number of dozen \( = x \). So \( R = 2.50x \).

Answer:

a. \( R = 2.50x \)
