Given:
Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster.
To find:
The graph that represents the set of heights that satisfy this requirement.
Solution:
Let x be the height required for the ride.
Guests must be at least 54 inches tall to be able to ride the roller coaster. It means required height is greater than or equal to 54.
So, 54 and all values above 54 are in the solution set.
Since, 54 is included in the solution set, therefore there is a closed circle at 54. All values above 54 are in the solution set, so everything to the right of the circle is shaded.
Therefore, the correct option is C.

Answer:
The amount invested in gold bullion by Mr. Eliot = $50,000
Step-by-step explanation:
Total amount of savings Me. Eliot ha s = $150,000
Let us assume the amount invested in gold bullion = $m
So, the amount invested in bank = $150,000 - m
Now, 5% on m =
So, the profit in gold bullion = 0.05 m
and 3% on (150,000 -m) =
= 4,500 - 0.03 m
So, the profit in bank = 4,500 - 0.03 m
Now, the total profit = $5,500
⇒Profit from gold bullion + ban = $5,500
⇒0.05 m + 4,500 - 0.03 m = $5,500
or, 0.02 m = 1000
⇒ m = 1000/0.02 = 50,000
Hence, the amount invested in gold bullion = m = $50,000
