Answer:
First, 7 Second, x^1/2
Step-by-step explanation:
Calculate for the values of the terms by substituting 1 to n for 1991, 2 for 1992, 3 for 1993, and so on up to 9 for 1999.
We may opt to solve for the A for the 9 terms such as below.
n = 1.
A₁ = 0.17(1²) - 1.02(1) + 6.67 = 5.82
A₂ = 0.17(2²) - 1.02(2) + 6.67 = 5.31
A₃ = 0.17(3²) - 1.02(3) + 6.67 = 5.14
A₄ = 0.17(4²) - 1.02(4) + 6.67 = 5.31
A₅ = 0.17(5²) - 1.02(5) + 6.67 = 5.82
A₆ = 0.17(6²) - 1.02(6) + 6.67 = 6.67
A₇ = 0.17(7²) - 1.02(7) + 6.67 = 7.86
A₈ = 0.17(8²) - 1.02(8) + 6.67 = 9.39
A₉ = 0.17(9²) - 1.02(9) + 6.67 = 11.26
The sum of these values is $62.58. The answer is not among the choices.
