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.

Like terms are terms that are the exact same excluding coefficients.
To combine like terms, add or subtract the coefficients.
Here are a few examples.
-3x^2+ 2x^2= -x^2
14xyz-12xyz=2xyz
12p-3p+8p= 17p
49/7 = 7 as a whole number
