Answer:
16a) $1,320 (<em>Set-up below)</em>
16b) (<em>See explanation below)</em>
17a) $21.90 <em>(Set-up below)</em>
17b) $708.10 (<em>See explanation below)</em>
Step-by-step explanation:
16a)
33,000 · 0.04 = 1,320
<u>Set-up:</u>
Whenever you are solving equations with percentages, it is easier to change them into decimal form. 4% is equal to 0.04 so we can multiply 33,000 by 0.04 to find the commision price.
16b)
Since a commision is taken out of the total of a sale, we know that if you doubled to sale, the commission would also double unless the percentage the salesperson is getting goes down or up. If the percentage does not change, they would still get double because they would be getting a larger amount because the total is larger.

17)
a)
110 · 0.03 = 3.3
275 · 0.03 = 8.25
200 · 0.03 = 6
145 · 0.03 = 4.35
3.3 + 8.25 + 6 + 4.35 = $21.90
<u>Set-up:</u>
Whenever you are solving equations with percentages, it is easier to change them into decimal form. 3% is equal to 0.03 so we can multiply each cost by 0.03 to find the commision price per item. After, we add up each separate commision price to get the total commision.
b)
110 + 275 + 200 + 145 = 730
730 - 21.9 = $708.10
<u>Quick Explanation:</u>
The store would only earn $708.10 because of the commision they are paying Heidi is equal to $21.90. The total sale cost earned is $730.00 and the commision comes out of that cost, the store only gets $708.10
