There has to be a total of 63 boxes each with a prize in them.

There are two types of prizes: The first type is $25 and second type is $100. 

If you make all the prizes $100, you will only end up with 27 prizes. ($2700 / 100), which is too little. 

If you make all the prizes $25, you will only end up with 108 prizes ($2700/ 25), which is too way many. 

The answer has to be combination of prizes More $25 prizes will have an outcome of more prizes in total. 
More $100 prizes will have an outcome of less prizes in total. 

The answer would come out to

48 prizes of $25 each ($1200) 
15 prizes of $100 each ($1500)

which adds to the full amount of $2700 with 63 prizes.

This is an exponential growth problem. Exponential growth can be expressed mathematically in the following way: 
y=a (1+r)^{t}.
Parameter a presents initial amount.
Parameter r is percentage increase. 
Parameter t is time.
An equation that would describe given problem is:
y=400 (1+0.02)^{t}
t is the time in years.
I attached the graph of this function.

Sq is an angle bisector m <qst=2x and m <qsr=3x-10 what is <rst
defon
Answer:
∠RST = 40°

Explanation:
We are given that:
SQ bisects angle RST.
This means that:
∠QST = ∠QSR
2x = 3x - 10
10 = 3x - 2x
x = 10

Therefore:
∠QST = 2x = 2(10) = 20°
∠QSR = 3x - 10 = 3(10) - 10 = 30 - 10 = 20°
Note that both angles are equal.

Now, we can get ∠RST as follows:
∠RST = ∠QST + ∠QSR
∠RST = 20 + 20 = 40°

Hope this helps :)
