Question

Lin plans to swim 12 laps in the pool. She has swum 9.75 laps so far.

How many laps does she have left to swim? Use y
for the number of laps that Lin has left to swim.

Answer 1

Lin plans to swim 12 laps and has already swum 9.75 laps, so the number of laps she has left to swim can be found by subtracting 9.75 from 12:

y = 12 - 9.75

Simplifying the right side:

y = 2.25

Therefore, Lin has 2.25 laps left to swim.
