Answer: 24 tests
Step-by-step explanation:
Ms. Carey graded 1/3 of the tests and still had 16 tests to go.
This means that the 16 tests represent the remaining proportion of the total number of tests:
= 1 - 1/3
= 2/3
2/3 of the total is equal to 16 tests. Assuming the total is x, the expression would be:
2/3x = 16
x = 16 ÷ 2/3
x = 16 * 3/2
x = 24 tests
Then the original price was $42
Because it is half off we multiply 21 by 2 and get 42.
4200ft divided by 20 ft per second divided by 60 seconds is 1400 minutes

The rule for this sequence is 'multiply by -6'.
Verification ↓
-3*(-6)18
18*(-6)-108
So the rule for the sequence is 'multiply by -6'
And the Common ratio is -6.
Hope that made sense !!
