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.

Solve for d.<br> d+ 4 = 16.21<br> d=
lutik1710 [3]

Answer:

d = 12.21

Step-by-step explanation:

1) Subtract 4 from both sides.

d = 16.21 - 4

2) Simplify 16.21 - 4 to 12.21.

d = 12.21

Check the answer!

⇒ d + 4 = 16.21

1. Let d = 12.21.

⇒ 12.21 + 4 = 16.21

2. Simplify 12.21 + 4 to 16.21

16.21 = 16.21

Done!

Thanks,

Eddie
