at the beginning of summer, sam could swim 12 laps. now, he can swim 15 laps. what is the percent change in the number of laps sam can swim? ?%

Answer

Explanation:

Step1: Find the difference in laps

$15 - 12=3$

Step2: Calculate the percent - change formula

Percent change=$\frac{\text{Change}}{\text{Original}}\times100%$. Here, the change is 3 and the original number of laps is 12. So, $\frac{3}{12}\times100%$.

Step3: Simplify the expression

$\frac{3}{12}\times100% = 0.25\times100%=25%$

Answer:

25%
