Answer:
an=12−1.5n
Step-by-step explanation:
The first term is 10.5.
The common difference is ...
9 - 10.5 = -1.5
The n-th term can be described by ...
an = a1 +d(n -1)
an = 10.5 -1.5(n -1) = 10.5 -1.5n +1.5 . . . . eliminate parentheses
an = 12 -1.5n

Daily profit, y, as a function of T-shirts sold, x, is
y = -10x² + 160x - 430
In order to generate $50 in daily profits, the number of T-shirts sold is determined by solving the equation
-10x² + 160x - 430 = 50
Divide through by -10.
x² - 16x + 43 = -5
x² - 16x + 48 = 0
Answer:
This quadratic equation can be solved by factorization.
Explanation:
Note that
48 = 4 x 12, and
4 + 12 = 16
Therefore
x² - 16x + 48 = (x - 4 )(x - 12 ) = 0
The solutions are
x - 4 = 0 => x = 4, and
x - 12 = 0 => x = 12
Answer: 8 months.
