Answer:

Problem 1.

If the plane can still load p no. of passengers , then,

p ≤ 78

Problem 2

With 6 servings of wings, Sarah can serve maximum 2 burgers.

Problem 3

x > 10 [where the passenger travels x miles by either Uber or Lift car]

Step-by-step explanation:

Problem 1

Let, the no. of passengers that the plane can still load is p.

Then, according to the question,

p ≤ (118 - 40)

⇒ p ≤ 78

Problem 2

Let, Sarah can serve x no. of wings and y no. of burgers.

Then according to the question,

6x + 3y < 45 ------------(1) and

x ≥ 4 --------------(2)

Now, for 6 servings of wings or for x = 6,

from (1)

3y < 9

⇒ y < 3

So, with 6 servings of wings, Sarah can serve maximum 2 burgers.

Problem 3

For, going x miles the Uber driver charges,

$ ( 3 + 0.5x)

while the Lift driver charges,

$ ( 2 + 0.6x)

So, the cost of Lift is greater than Uber when

2 + 0.6x > 3 + 0.5x

⇒0.1x > 1

⇒x > 10
