Answer:
y = 3^(1 + x)
Step-by-step explanation:
Notice that each time x increases by 1, y increases by a factor of 3.
Thus, the required equation has the form y = 3^x.
Check: If x = 0, do we get 3? No. Therefore we must modify the exponent:
y = 3^(1 + x)
Check: If x = 0, do we get 3? 3^(1 + 0) = 3 (correct)
If x = 2, do we get 27? 3(1 + 2) = 3^3 + 27 (correct)
If you need to write a number as a decimal, it means that you need to write is a an x divided by a power of 10.
you can use this formula:

now let's multiply both sides by 10:

and simplyfy:
(by dividing the first fraction's elements by 5)

change improper fraction into a mixed number

and 1 over 3 is 0.33333...
so the answer is 1.333333 - we can also write it as 1.(3)
3 letters to US = 3*0.94 = 2.82
2 local letters = 2*0.44 = 0.88
checking: 2.82+0.88 = 3.70
to get rid out of 0.04 cents you have to multiply it by 5. so total number of letters would be 5.

Step-by-step explanation:
Total no. of buttons = 300 + 700 + 1000
+ 500 = 2500
Possibility for a person to pick a pink button = 300/2500 = (3/25)%
Amount of pink buttons she can expect her friends to pick = 50(3/25) = 6
She can expect to make 6 pink barrettes.
