Question

Brice gets $40 per day as wages and $7.50 on commission for every spear gun he sells in a day. His weekly earning goal is $500. Write an equation to determine how many spear guns Brice must sell in a day to meet his weekly earning goal.

a. 40s + 500 = 7.50
b. 7.50s + 500 = 40
c. 7.50s + 40 = 500
d. 40s + 7.50 = 500​

Answer 1

The equation to determine how many spear guns Brice must sell in a day to meet his weekly earning goal is 7.50s + 40 = 500. Brice must sell approximately 61.33 spear guns in a day to meet his weekly earning goal.

Step-by-step explanation:

The equation to determine how many spear guns Brice must sell in a day to meet his weekly earning goal can be written as:

7.50s + 40 = 500

Where:

• s represents the number of spear guns Brice sells in a day
• 7.50 represents the commission per spear gun sold
• 40 represents Brice's daily wages
• 500 represents Brice's weekly earning goal

To find the value of s, we can solve this equation:

1. Subtract 40 from both sides of the equation: 7.50s = 500 - 40
2. Combine like terms: 7.50s = 460
3. Divide both sides of the equation by 7.50: s = 460 / 7.50

Therefore, Brice must sell approximately 61.33 spear guns in a day to meet his weekly earning goal.
