The equation to find the amount that Lila still needs will be 80 + c = 120 and she'll need to save $40
Cost of the class = $120
Amount that has been saved by Lila = $80
In this case, we have been given the cost of the class and the amount that Lila has saved, therefore, in order to be able to calculate the amount that's left for the money to be completed, one has to subtract. This will be:
= Cost of class - Total amount saved
= $120 - $80
The equation 80 + c = 120 can also be used . C = 120 - 80 = 40
Therefore, based on the above calculation, Lila still needs to save $40.
