The price of the chandelier was first increased by 45%, and then by another 20%, by what percentage

The price of the chandelier was first increased by 45%, and then by another 20%, by what percentage did the price become higher?

To complete the task, we denote the initial cost for x. Now we need to raise x by 45%. First, let’s find what is equal to 45% of x. To find the percentage of the number, multiply this number by the percentage, and then divide the result by one hundred.
x * 45/100 = x * 0.45 = 0.45x.
Increase x by 0.45x.
x + 0.45x = 1.45x.
We will increase the received value by 20%.
1.45x + 0.2 * 1.45x = 1.45x + 0.29x = 1.74x.
Let’s calculate by what percentage the price has become higher.
1.74x – x = 0.74x.
0.74x / x * 100 = 74%.
Answer: 74%.
