Step-by-step explanation:

When you have an equation with an absolute value, you must consider two options: one with a positive result and another one with a negative result.

$x-55 = 4.2\\x = 4.2 + 55\\x = 59.2\\\\And\\\\x-55 = -4.2\\x=-4.2 + 55\\x = 50.8$

In this case you need the maximum safe driving speed which is 59.2 miles per hour

e-lub [12.9K]

Answer:

$ 1250

Step-by-step explanation:

output = 50 units per day

average total cost = $ 60

total cost = output × average total cost =50 × 60 = $ 3000

total variable cost = output × average variable cost = 35 × 50 = $ 1750

total cost = total fixed cost + total variable cost

total fixed cost = total cost - total variable cost = $ 3000 - $ 1750 = $ 1250
