Percent of Increase Word Problems

Hello and welcome! We’re focusing today on a fascinating mathematical topic: percent of increase word problems. We’ve got some exciting scenarios to consider and we’ll walk through these calculations together. It’ll be as simple as counting 1, 2, 3. Let’s start!
Before we start, let’s be clear on what percent of increase means. It’s a way of expressing the growth of a quantity in terms of the original amount. Simply put, it’s a measure of how much something has grown as a proportion of the original size.
For all you math enthusiasts, the formula for calculating the percentage of increase is: (Amount of increase / Original Amount) × 100or(Increase in Quantity / Original Quantity) × 100

Problem #1Let’s consider a basic problem: If Jacob has 50 marbles and during a lucky streak, he wins 20 more. What is the percent of increase in his marbles?First, figure out the increase – which is 20 marbles (the marbles he won). Then, divide this increase by the original quantity, which is 50 marbles. What do we get?20 divided by 50 gives 0.4. To convert this into percentage, simply multiply this ratio by 100. Thus, you will get 40%. So, Jacob’s marbles increased by 40%.

Problem #2Great job so far! Let’s try another. Imagine, you used to earn $30,000 yearly. After a fantastic performance review, your income increased to $36,000. What is the percent of increase?Again, find the increase: $36,000 – $30,000 equals $6,000. Then divide this increase by the original amount, $30,000. Let’s see the magic!$6,000 divided by $30,000 equals 0.2. Multiplying by 100 gives you a 20% increase in your earnings. Congratulations on your raise!Problem #3Feeling confident? Let’s not stop there. What if you had 500 Instagram followers and over a month, you gained 75 more. What’s the percent of increase in your followers?Find the increase, which here is 75 followers. Divide this by the original quantity, 500 followers.The good news? 75 divided by 500 is 0.15. After converting into a percentage, you will find there’s been a 15% increase in your followers. Your popularity is increasing!
Did you notice that all these percent of increase problems follow the same pattern? The same basic steps apply: find the increase, divide it by the original amount, and then multiply by 100 to get your percentage.
