Step-by-step explanation: Number of water bottles in March = 4,100 + 7% of 4,100
= 4,100 + 287
= 4,387
Number of water bottles in April = 4,387 + 500
= 4,887
Percent increase from February to April = ((4,887 - 4,100) / 4,100) x 100%
= (787 / 4,100) x 100%
= 19.19%
Therefore, the percent increase in the number of water bottles the company manufactured from February to April is approximately 19%.
