Mike is saving money for a new bike that costs $180.00. If m represents the amount of money he has saved so far, which expression represents the amount of money, in dollars, he still needs to save?

a. 180 + m
b. 180 - m
c. 180 ' m
d. 180 . m

b. 180 - m

thank you, Ms.sue

You're welcome, John.

It's C

To find the expression that represents the amount of money Mike still needs to save, we need to subtract the amount of money he has saved (m) from the cost of the bike ($180.00).

Therefore, the expression that represents the amount he still needs to save is:

b. 180 - m
