Question

Write an equation for the number of blocks Tegan still needs to make, m, when she has completed c blocks.

Answer 1

68-c=m
Btw my name is Tegan xD

Answer 2

We are given:

The number of blocks Tegan still needs to make = m.

The number of blocks Tegan has completed = c.

Total number 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.
