Question

Kate's swim coach informs her that she only has 35% of her workout left. Kate has swum 26 laps so far.

How many laps will Kate swim in all?

Answer 1

Well so far, Kate has saw 65% of her workout

65% = 26 0.65 *t = 26 t=26 t\0.65=40 laps

Answer 2

You are given Kate’s number of laps of 26. She was also informed that she has only 35% left to finish her workout. Assuming a basis of 100%. Subtract 100% to 35% equals 65%. This 65% is the workout that Kate has achieved. This is equal to 26 laps. So,  

0.65L = 26
L = 40 laps  
Kate has 40 laps left to achieve a 100% of her workout.
