Alicia planted 45 tulip bulbs last year.This year she plans to plant 65 bulbs. Find the percent of increase in the number of tulip bulbs to the nearest tenth.
To find the percent increase in the number of tulip bulbs, you need to compare the difference between the two numbers (last year's and this year's bulbs) to the original number (last year's bulbs). Here's how you can calculate it:
1. Find the difference between the two numbers: 65 (this year's bulbs) - 45 (last year's bulbs) = 20 bulbs.
2. Calculate the percent increase by dividing the difference by the original number, and then multiplying by 100: (20 / 45) * 100 = 44.4%.
Therefore, the percent increase in the number of tulip bulbs is approximately 44.4% to the nearest tenth.
