Answer: $69.75.


Step-by-step explanation:

Given: Cost of textbook before tax=$65.49

The tax on the textbook = 6.5%

∴ The tax amount = 6.5% of $65.49

=\frac{65}{1000}\times65.49=4.25685\approx4.26

⇒The tax amount = $4.26

The total cost of the textbook=Cost of textbook before tax+tax amount

=$65.49+$4.26

=$69.75

∴ The total cost of the textbook is $69.75.

Brainliest for the correct answer with the correct working out! If n is an integer, what numbers of n such that −1 ≤ n + 7 <
8_murik_8 [283]

Answer:

−1 ≤ n + 7 < 9

To solve a compound inequality separate it into two inequalities

That is

n + 7 ≥ - 1 and

n + 7 < 9

Solve the inequality

n + 7 ≥ -1

n ≥ - 8

and

n + 7 < 9

n < 7 - 9

n < 2

Find the intersection

The final answer is

-8 ≤ n < 2

Hope this helps
