Answer:
The first option is the correct option
Step-by-step explanation:
From the question the slope AC is evaluated as
And the slope of line CB is mathematically evaluated as
Now for lines that are perpendicular to each other then the product of their slope should be equal to -1
So if 
Then

Answer:
9.25 p + 8.90 t ≥ 100 describes the relationship between p and the t for Michael to earn at least $100.
Step-by-step explanation:
p = Number of hours worked at the pet store
Earning per hour at pet store = $9.25
t = Number of hours worked as a telemarketer
Earning per hour at telemarketing job = $8.90
Now, total amount earned at pet store after working p hours = p x $9.25
and total amount earned at tele job after working t hours = t x $8.90
Now, according to the question
Total money earned at pet store + Total earning at telemarketing job = At least $100
⇒ 9.25 p + 8.90 t ≥ 100
Hence, 9.25 p + 8.90 t ≥ 100 describes the relationship between p and the t .
