3y + 5 = 47
Subtract the 5 so you have 3y on the left side and move it to the other side.
Now it’s:
3y = 47-5
3y = 42
Now, divide 3y by 3, so we get y by itself. Do the same thing to the other side.
y = 14
B = 2 + g . . . (1)
g = 6 + r . . . (2)
r = 6 + p . . . (3)
Putting (3) into (2) gives:
g = 6 + 6 + p = 12 + p . . . (4)
Putting (4) into (1) gives:
b = 2 + 12 + p = 14 + p . . . (5)
b + g + r + p = 1200
2 + g + 6 + r + 6 + p + p = 1200
2 + 12 + p + 6 + 6 + p + 6 + p + p = 1200
32 + 4p = 1200
4p = 1200 - 32 = 1168
p = 292
From (5), b = 14 + p = 14 + 292 = 306
Therefore, there are 306 blue mables.

Answer:
She is actually paying a rate of 7.36% of interest.
Step-by-step explanation:
The real interest rate, as a decimal, is given by:

In which r is the interest rate and n is the number of compoundings during an year.
The nominal rate on Sandra's loan is 7.125%, compounded monthly:
This means that 
So

As a percentage: 1.0736*100 = 107.36% - 100% = 7.36%
She is actually paying a rate of 7.36% of interest.
