Answer:

[4, 6]

Step-by-step explanation:

∑ₙ₌₁°° (x − 5)ⁿ / n²

Use ratio test.

lim(n→∞)│aₙ₊₁ / aₙ│< 1

lim(n→∞)│[(x − 5)ⁿ⁺¹ / (n+1)²] / [(x − 5)ⁿ / n²]│< 1

lim(n→∞)│[(x − 5) n² / (n+1)²│< 1

│x − 5│< 1

-1 < x − 5 < 1

4 < x < 6

If x = 4, ∑ₙ₌₁°° (4 − 5)ⁿ / n² = ∑ₙ₌₁°° (-1)ⁿ / n², which converges.

If x = 6, ∑ₙ₌₁°° (6 − 5)ⁿ / n² = ∑ₙ₌₁°° 1 / n², which converges.

So the interval of convergence is [4, 6].

Vera_Pavlovna [14]

Answer: $107

Step-by-step explanation:

Tip = 20 % of $90

= 20/100 × $90

=$18

Sales tax at 10% = 10/100 × $90

= $9

Total cost= $90 + $18 + $9

= $107
