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

Using the formula for simple interest
(1000 X 5 X 2)/100
the answer is $100 but to the nearest cent it is 10000cents
66 inches just multiply 5 by 12 the add the 6
The mistake that was made is that she should of multiplied the fractions by the exponents first
