Tegan needs to make 686868 more snow blocks to finish building an igloo. Write an equation for the number of blocks Tegan still
Keith_Richards [23]

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.
