The answer is 22.94 because of reasons and math and decimals and stuffy I'm not going to go in to detail somebody else can because I'm not with the math stuff

Answer:
We are given:
No: of blocks Tegan still needs to make = m.
No: of blocks Tegan has completed = c
Total No:of more snow blocks need to make = 68 .
Total number of more snow blocks need to make = Total number of blocks -  The number of blocks Tegan has completed.
m = 68 - c.
Therefore, the equation for the number of blocks Tegan still needs to make, m, when she has completed c blocks is
m = 68 - c.
For example.
Suppose if c = 10, it means Tegan still needs to make 68-10 = 58 block.
