The answer to 2 1/3 - 2/3 is 1 2/3
$1602 would be the amount paid for 3 years of lessons.
First you need to divide 64 by 75 and then multiply by 100 which is 85.3% which then you need to find the average of the 2 which will be (85.3+x)/2=88 where x= the value of the second test.
Then you will need to isolate the x with the following steps:
- multiply each side by 2 making it 85.3+x=176
- Subtract 85.3 from each side
- this results in 90.7
