5. Mrs. Neri works part time at an electronics store. She is paid a weekly salary plus a

commission based on her total sales. The table shows her total sales and her total pay

for the last two weeks.

Week/1

Total Sales

/ $500

to

Total Pay

$425

Week/2

Total sales

$350

Total pay 395

Based on the data in the table, which equation represents Samantha's total pay, y, as

a function of her total sales, x?

A) y = 0.6x + 125

B) y = 0.2% + 325

C) y = 1.6% - 95

The equation that represents Samantha's total pay as a function of her total sales is B. y = 0.2x + 325

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Total Sales Total Pay

Week 1 $ 500 $ 425

Week 2 $ 350 $ 395

2. Let's find out the equation that represents Samantha's total pay as

a function of her total sales, this way:

Week 1:

A) y = 0.6x + 125 = 0.6 * 500 + 125 = 300 + 125 = 425 Correct

B) y = 0.2x + 325 = 0.2 * 500 + 325 = 100 + 325 = 425 Correct

C) y = 1.6x - 95 = 1.6 * 500 - 95 = 800 - 95 = 705 Incorrect

Week 2:

A) y = 0.6x + 125 = 0.6 * 350 + 125 = 210 + 125 = 335 Incorrect

B) y = 0.2x + 325 = 0.2 * 350 + 325 = 70 + 325 = 395 Correct

C) y = 1.6x - 95 = 1.6 * 350 - 95 = 560 - 95 = 465 Incorrect

The equation that represents Samantha's total pay as a function of her total sales is B. y = 0.2x + 325
