64 more laps are needed to reach her goal
Given that Liz is traning for a swim meet her goal is to swim 100 laps
she swam 12 laps in the pool on each of 3 days
To find: Number of laps more needed to swin to reach her goal
From given information,
Liz swam 12 laps in the pool on each of 3 days, Which means Liz swam 12 laps on each of 3 days
So number of laps completed in 3 days:
number of laps completed in 3 days = 3 x 12 = 36 laps
So number of laps more needed to swin to reach her goal can be calculated by subtracting number of laps completed in 3 days from her goal of 100 laps
number of laps more needed to swin to reach her goal = 100 laps - 36 laps = 64 laps
If "L" is the number of laps more needed to swin to reach her goal, we can frame a equation as:
L = 100 - 36 = 64
So 64 more laps are needed to reach her goal
