Hi there!
To figure out the value of x, we can use a proportion. Here's the proportion we'd use: 15/7 + x = 9/x. Next, we'll need to cross-multiply in order to get an equation that we are able to solve: 9(7 + x) = 15x. Then, we'll distribute the terms: 63 + 9x = 15x. Lastly, we'll subtract 9x from each side and divide to find the value of x: 6x = 63 | x = 10.5.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Answer:
47.84%
Step-by-step explanation:
The easiest method to solve this exercise is to assume that the starting diesel price is 100 reais.
Now we will calculate each increase with our assumption:
1. Initial price plus 10% increase, therefore:
100 + 100 * 0.1 = 110 reais
2. Additional 20% increase in relation to 110 reais:
110 + 110 * 0.2 = 132 reais
3. Additional 12% increase in relation to 132 reais:
132 + 132 * 0.12 = 147.84 reais.
What it means is that the price would be 147.84 reais.
Since our assumption is 100, we can know that there was an increase of almost 47.84% in relation to the initial price that we assumed at the beginning.
