Answer 1

Kendall and Sophia swam (2n - 12) laps together

Solution:

Given that, Kendall Swam (n) laps in the pool

To find: Number of laps swam together

From given statement,

Number of laps by Kendall = n

Also, Sophia swam 12 less than Kendall

Therefore, number of laps swam by Sophia is 12 less than the number of laps by Kendall

Number of laps by Sophia = Number of laps by Kendall - 12

Number of laps by Sophia = n - 12

How many laps did they swim altogether ?

Number of laps swam together = Number of laps by Kendall + Number of laps by Sophia

Number of laps swam together = n + n - 12 = 2n - 12

Thus they swam (2n - 12) laps together
