The percentages for each acid are:
- 0% acid ⇒ percentage disolved = 0%
- 33% acid ⇒ percentage disolved = 1%
- 66% acid ⇒ percentage disolved = 2%
- 100% acid ⇒ percentage disolved = 4.2%
<h3>
How to get the percentages?</h3>
Here we just need to use the given formula:

For the 0% acid, the initial and final mass are the same:
initial mass = final mass = 10.3g
Then the percent dissolved is:

For the 33% acid we have:
- initial mass = 10.1g
- final mass = 10g
Then:

For the 66% acid:
- initial mass = 10g
- final mass = 9.8g

for the 100% acid:
- initial mass = 9.9g
- final mass = 9.5g

Every week, the price of jeans reduced by $6.
The total value of price reduction over the 7-week period can be calculated as the product of price reduction per week and the number of weeks. Thus,
Total price reduction = price reduction per week x number of weeks
= $6 x 7
=$ 42
