Given:

They need at least 50 total rooms.

Already reserved rooms = 16

1 Block = 8 rooms

Cost of one block = $900

To find:

The inequality for the given scenario.

Solution:

(1)

Let B represent the number of additional blocks that Joe reserves.

1 Block = 8 rooms

B Block = 8B rooms

Total number of rooms = 16 + 8B

They need at least 50 total rooms. It means, total number of rooms must be great than or equal to 50.

[tex]16+8B\geq 50[/tex]

Therefore, the correct option is B.

(2)

We have,

[tex]8B\geq 50-16[/tex]

[tex]8B\geq 34[/tex]

Divide both sides by 8.

[tex]B\geq \dfrac{34}{8}[/tex]

[tex]B\geq 4.25[/tex]

So, least number of required blocks is 5.

Least amount of additional money is

[tex]5\times \$900=\$4500[/tex]

Therefore, the least amount of additional money Joe can spend to get the rooms they need is 4500 dollars.
