Answer:
1/2 dozen of one score is 30%.

1 score = 20 units.
By using this conversion, we get
6/2 times 100=30%
So 1/2 dozen of one score is 30%

Having obtained:

the next thing to do is collect the first three terms and write them as the square of a binomial, and also collect the last two terms, writing each of them with a denominator equal to 4a^2
We have:

.
Then, we take

to the right side and write these two terms as one:

.
Next, we take the square root of both sides, which has been shown in the solution.
Next, we have to take b/2a to the right hand side as -(b/2a), and removing the square in the denominator of the right hand side expression:

.

Smart Dot, multiply the cost per hour by number of hours (t) and add to the monthly fee:
C = 0.50t + 12
Communication plus: Multiply the cost per hour by number of hours (t)
C = 2.50t
