i took 3 times nine then i took the answer: 21 minus 12 and that equals nine
New class average: 83
The original average: 82
And if there are 12 students, the total sum of all 12 tests should be
82 x 12 = 984
Then to find the average of the new tests
Add 12 points to the original sum
984+12 = 996
Then divide by 12 to find the new average
996/12 = 83
Hello there,
Okay first we would need to write down what does the problem gives us that we already know...
- she bought 3 CDs each with the same price
- she paid a total of $35.40
- the tax was $2.70
Now in order for us to solve we need to subtract the tax from the total price... 35.40 - 2.70 = 32.70.
Since we have the price before the tax now we just have to divide 32.70 by 3 and by doing that you would get 10.90.
Each CD is $10.90.
Hope I helped,
Amna
