Answer:

21%

Step-by-step explanation:

Another 10% increased means it becomes 110*110/100 = 121. The first 10% increase means the second 10% increase will be an actual 11% increase from the original, so it will be a total of 21%.

Answer:

<h2><em><u>21%</u></em></h2>

Step-by-step explanation:

Because the first 10% increase is calculated as 10% of what you started with. The second 10% is 10% of what you started with plus 10% of the increase caused by the original 10% increase.

Let's do the maths…

Let's start with 100 to make things easy.

We know that 10% of 100 is 10.

We know that 20% of 100 is 20.

So if we increase 100 by 10% we get 110.

If we increase 100 by 20% we get 120.

Now lets do the 10% plus 10%.

From the first 10% increase we were left with 110.

Now if we take 10% of the 110 we have 11.

<u>Add that to the 110 and we get 121.</u>

<em>This is why people are surprised how quick a lone can rise if we don't pay it off. We are paying interest on the basic sum plus interest on the interest, then interest on the interest on the interest.</em>

lina2011 [118]

Let's call dimes x and the quarters x+3 since we have 3 more of them.

x+x+3=45

2x=42

x=21

we have 21 dimes and 23 quarters

21*0.10=2.1

23*0,25=5.98

if we add those together it equals 8.08
